We also summarize methods for computing one-loop amplitudes, which are used as inputs to the computation of two-loop anomalous dimensions, and we explain how the structure of rational terms and judicious renormalization scheme choices can lead to additional vanishing terms in the anomalous dimension matrix at two loops. We describe the two-loop implications for the Standard Model Effective Field Theory (SMEFT). As a by-product of this analysis we verify a variety of one-loop SMEFT anomalous dimensions computed by Alonso, Jenkins, Manohar and Trott. \\ ( https://arxiv.org/abs/2005.12917 , 131kb) ------------------------------------------------------------------------------ \\ arXiv:2005.12923 Date: Tue, 26 May 2020 18:00:02 GMT (204kb,D) Title: General relativistic non-ideal fluid equations for dark matter from a truncated cumulant expansion Authors: Alaric Erschfeld, Stefan Floerchinger, Maximilian Rupprecht Categories: hep-ph astro-ph.CO Comments: 10 pages, 1 figure \\ A new truncation scheme based on the cumulant expansion of the one-particle phase-space distribution function for dark matter particles is developed. Extending the method of moments in relativistic kinetic theory, we derive evolution equations which supplement the covariant conservation of the energy-momentum tensor and particle number current. Truncating the cumulant expansion we obtain a closed, covariant and hyperbolic system of equations which can be used to model the evolution of a general relativistic non-ideal fluid. As a working example we consider a Friedmann-Lema\^itre-Robertson-Walker cosmology with dynamic pressure and solve for the time evolution of the effective equation of state parameter. \\ ( https://arxiv.org/abs/2005.12923 , 204kb) ------------------------------------------------------------------------------ \\ arXiv:2005.12936 Date: Tue, 26 May 2020 18:00:34 GMT (292kb,D) Title: Modeling of $t$-channel single top-quark production at the LHC Authors: Jun Gao, Edmond L. Berger Categories: hep-ph Comments: 6 pages, 5 figures \\ We study the modeling of $t$-channel single top-quark production at Large Hadron Collider (LHC) energies. We compare predictions at next-to-next-to-leading order in a 5-flavor scheme to those of next-to-leading order in a 4-flavor scheme, finding the two schemes agree within a few percent in general for the shape of kinematic distributions of the top quark. The predictions in the 5-flavor scheme show strong stability for both normalization and distributions, and are superior to those of the 4-flavor scheme at comparable orders. We present comparisons of the predictions with LHC data. Our findings provide clear theoretical guidance for precision studies of single top-quark physics at the LHC. \\ ( https://arxiv.org/abs/2005.12936 , 292kb) ------------------------------------------------------------------------------ \\ arXiv:2005.12952 Date: Tue, 26 May 2020 18:15:30 GMT (225kb) Title: Nucleon and dinucleon decays to leptonic final states in a left-right symmetric model with large extra dimensions Authors: Sudhakantha Girmohanta Categories: hep-ph Comments: 23 pages, 1 figure Report-no: Stony Brook preprint YITP-SB-2020-11 \\ We consider baryon-number-violating nucleon and dinucleon decays to leptonic final states in the context of a left-right symmetric (LRS) model with large extra dimensions. Specifically, we study (a) nucleon to trilepton decays with $\Delta B=-1$ and $\Delta L=-3$, and (b) dinucleon to dilepton decays with $\Delta B=-2$ and $\Delta L=-2$. In the LRS model, $B-L$ is gauged and is spontaneously broken by a Higgs vacuum expectation value $v_R$, which characterizes the scale at which processes violating $B-L$ occur. We show that together with the lower bound on $v_R$ from experimental limits on $n$-$\bar n$ oscillations, constraints from searches for other nucleon decay modes imply sufficient suppression of these nucleon to trilepton and dinucleon to dilepton decay modes in this model to agree with experimental bounds. \\ ( https://arxiv.org/abs/2005.12952 , 225kb) ------------------------------------------------------------------------------ \\ arXiv:2005.12967 Date: Tue, 26 May 2020 18:45:08 GMT (305kb,D) Title: $J/\psi$ meson production in association with an open charm hadron at the LHC: a reappraisal Authors: Hua-Sheng Shao Categories: hep-ph hep-ex nucl-ex nucl-th Comments: 31 pages, 19 figures, 7 tables \\ We critically (re)examine the associated production process of a $J/\psi$ meson plus an open charm hadron at the LHC in the proton-proton ($pp$) and proton-lead ($p{\rm Pb}$) collisions. Such a process is very intriguing in the sense of tailoring to explore the double parton structure of nucleons and to determine the geometry of partons in nuclei. In order to interpret the existing $pp$ data with the LHCb detector at the centre-of-mass energy $\sqrt{s}=7$ TeV, we introduce two overlooked mechanisms for the double parton scattering (DPS) and single parton scattering (SPS) processes. Besides the conventional DPS mode, where the two mesons are produced almost independently in the two separate scattering subprocesses, we propose a novel DPS mechanism that the two constituent (heavy) quarks stemming from two hard scatterings can form into a composite particle, like the $J/\psi$ meson, during the hadronisation phase. However, it turns out the corresponding contribution is small in $J/\psi+c\bar{c}$ hadroproduction. On the contrary, we point out that the resummation of the initial state logarithms due to gluon splitting into a charm quark pair is crucial to understand the LHCb measurement, which was overlooked in the literature. We perform a proper matching between the perturbative calculations in different initial-quark flavour number schemes, generically referring to the variable flavour number scheme. The new variable flavour number scheme calculation for the process strongly enhance the SPS cross sections, almost closing the discrepancies between theory and experiment. Finally, we present our predictions for the forthcoming LHCb measurement in $p{\rm Pb}$ collisions at $\sqrt{s_{NN}}=8.16$ TeV. Some interesting observables are exploited to set up the control regions of the DPS signal and to probe the impact-parameter dependent parton densities in lead. \\ ( https://arxiv.org/abs/2005.12967 , 305kb) ------------------------------------------------------------------------------ \\ arXiv:2005.13010 Date: Tue, 26 May 2020 20:13:32 GMT (7600kb,D) Title: Study of Jet Quenching in Relativistic Heavy-Ion Collisions Authors: Fabio Canedo Categories: hep-ph \\ In this work, we investigate possible impacts that the behavior of the Quark-Gluon Plasma might have on Jet Observables. We choose JEWEL (Jet Evolution With Energy Loss) for this study. We have coupled JEWEL with $\rm T_RENTo$ and also with MC-KLN+vUSPhydro for simulations. The simulations were performed for PbPb collisions at $\sqrt{s_{NN}} = 2.76 \, {\rm TeV}$ in the $0-10\%$ centrality class. We have found that jet shape observables are mainly unchanged by the inclusion of realistic hydrodynamics and initial conditions in these settings. We also made calculations for the jet $v_2$. In this case, we have found that initial conditions do not affect this observable. In the case of realistic hydrodynamics, there is an improvement in the description of data. \\ ( https://arxiv.org/abs/2005.13010 , 7600kb) ------------------------------------------------------------------------------ \\ arXiv:2005.13016 Date: Sun, 24 May 2020 20:44:10 GMT (7kb) Title: A Higgs Doublet + Higgs Singlet Scheme with Negative Kinetic Term for Neutrino Mass Generation Authors: Jianlong Lu Categories: hep-ph Comments: 8 pages \\ In this paper, we propose a scheme for neutrino mass generation. A Higgs singlet is introduced in the Standard Model of particle physics (SM). All of this new singlet and the charged and neutral Higgs fields in the original Higgs doublet are assumed to have nonzero vacuum expectation values (VEVs). The normal hierarchy of neutrino masses is evidently preferred in our scheme. The neutrino masses are explicitly calculated. \\ ( https://arxiv.org/abs/2005.13016 , 7kb) ------------------------------------------------------------------------------ \\ arXiv:2005.13063 Date: Tue, 26 May 2020 21:53:07 GMT (429kb,D) Title: Rapidity Logarithms in SCET Without Modes Authors: Matthew Inglis-Whalen, Michael Luke, Aris Spourdalakis Categories: hep-ph Comments: 22 pages, 4 figures \\ We re-examine observables with rapidity divergences in the context of a formulation of Soft-Collinear Effective Theory in which infrared degrees of freedom are not explicitly separated into modes. We consider the Sudakov form factor with a massive vector boson and Drell-Yan production of lepton pairs at small transverse momentum as demonstrative examples. In this formalism, rapidity divergences introduce a scheme dependence into the effective theory and are associated with large logarithms appearing in the soft matching conditions. This scheme dependence may be used to derive the corresponding rapidity renormalization group equations, and rates naturally factorize into hard, soft and jet contributions without the introduction of explicit modes. Extending this formalism to study power corrections is straightforward. \\ ( https://arxiv.org/abs/2005.13063 , 429kb) ------------------------------------------------------------------------------ \\ arXiv:2005.13067 Date: Tue, 26 May 2020 22:19:51 GMT (1738kb,D) Title: The Constituent Counting Rule and Omega Photoproduction Authors: Trevor Reed, Christopher Leon, Frank Vera, Lei Guo, and Brian Raue Categories: hep-ph nucl-ex nucl-th Comments: 6 pages, 7 figures \\ The constituent counting ruling (CCR) has been found to hold for numerous hard, exclusive processes. It predicts the differential cross section at high energies and fixed $\cos \theta_{c.m.}$ should follow $\frac{d \sigma}{dt} \sim \frac{1}{s^{n-2}}$, where $n$ is the minimal number of constituents involved in the reaction. Here we provide an in-depth analysis of the reaction $\gamma p \rightarrow \omega p$ at $\theta_{c.m.}\sim 90^\circ$ using CLAS data with an energy range of $s = 5 - 8$ GeV$^2$, where the CCR has been shown to work in other reactions. We argue for a stringent method to select data to test the CCR and utilize a Taylor-series expansion to take advantage of data from nearby angle bins in our analysis. Na\"{i}vely, this reaction would have $n=9$ (or $n=10$ if the photon is in a $q\bar{q}$ state) and we would expect a scaling of $\sim s^{-7}$ ($s^{-8}$). Instead, a scaling of $s^{-(9.08 \pm 0.11)}$ was observed. Explanations for this apparent failure of the na\"{i}ve CCR assumptions are examined. \\ ( https://arxiv.org/abs/2005.13067 , 1738kb) ------------------------------------------------------------------------------ \\ arXiv:2005.13068 Date: Tue, 26 May 2020 22:23:32 GMT (807kb,D) Title: Supernovae neutrino detection via coherent scattering off silicon nuclei Authors: Ana Luisa Foguel, Eduardo Souza Fraga, Carla Bonifazi Categories: hep-ph astro-ph.HE Comments: 7 pages, 6 figures \\ Low-energy neutrinos are clean messengers from supernovae explosions and probably carry unique insights into the process of stellar evolution. We estimate the expected number of events considering coherent elastic scattering of neutrinos off silicon nuclei, as would happen in Charge Coupled Devices (CCD) detectors. The number of expected events, integrated over a window of about 18 s, is $\sim$ 4 if we assume 10 kg of silicon and a supernovae 1 kpc away. For a a distance similar to the red supergiant Betelgeuse, the number of expected events increases to $\sim$ 30 - 120, depending on the supernovae model. We argue that silicon detectors can be effective for supernovae neutrinos, and might possibly distinguish between models for certain target masses and distances. \\ ( https://arxiv.org/abs/2005.13068 , 807kb) ------------------------------------------------------------------------------ \\ arXiv:2005.13136 Date: Wed, 27 May 2020 02:48:34 GMT (3639kb) Title: Modified MIT Bag Models: Thermodynamical consistency, stability windows and symmetry group Authors: Luiz L. Lopes, Carline Biesdorf, D\'ebora P. Menezes Categories: hep-ph astro-ph.HE nucl-th Comments: 12 pages, 9 figures \\ In this work we study different variations of the MIT bag model. We start with the so called non-ideal bag model and discuss it in detail. Then we implement a vector interaction in the MIT bag model that simulates a meson exchange interaction and fix the quark-meson coupling constants via symmetry group theory. At the end we propose an original model, inspired by the Boguta-Bodmer models, which allows us to control the repulsion interaction at high densities. For each version of the model we obtain a stability window as predicted by the Bodmer-Witten conjecture and discuss its thermodynamical consistency. \\ ( https://arxiv.org/abs/2005.13136 , 3639kb) ------------------------------------------------------------------------------ \\ arXiv:2005.13280 Date: Wed, 27 May 2020 11:14:34 GMT (32kb,D) Title: Modified majoron model for cosmological anomalies Authors: Gabriela Barenboim and Ulrich Nierste Categories: hep-ph astro-ph.CO astro-ph.HE Comments: 5 pages, 1 figure Report-no: IFIC/20-23, TTP20-023, P3H-20-022 \\ The vacuum expectation value $v_s$ of a Higgs triplet field $\Delta$ carrying two units of lepton number $L$ induces neutrino masses $\propto v_s$. The neutral component of $\Delta$ gives rise to two Higgs particles, a pseudoscalar $A$ and a scalar $S$. The most general renormalizable Higgs potential $V$ for $\Delta $ and the Standard-Model Higgs doublet $\Phi$ does not permit the possibility that the mass of either $A$ or $S$ is small, of order $v_s$, while the other mass is heavy enough to forbid the decay $Z\to A S$ to comply with LEP 1 data. We present a model with additional dimension-6 terms in $V$, in which this feature is absent and either $A$ or $S$ can be chosen light. Subsequently we propose the model as a remedy to cosmological anomalies, namely the tension between observed and predicted tensor-to-scalar mode ratios in the cosmic microwave background and the different values of the Hubble constant measured at different cosmological scales. Furthermore, if $\Delta$ dominantly couples to the third-generation doublet $L_\tau=(\nu_\tau,\tau)$, the deficit of $\nu_\tau$ events at IceCube can be explained. The singly and doubly charged triplet Higgs bosons are lighter than 280 GeV and 400 GeV respectively, and could be found at the LHC. \\ ( https://arxiv.org/abs/2005.13280 , 32kb) ------------------------------------------------------------------------------ \\ arXiv:2005.13341 Date: Wed, 27 May 2020 13:13:26 GMT (171kb,D) Title: Precise predictions for double-Higgs production via vector-boson fusion Authors: Fr\'ed\'eric A. Dreyer, Alexander Karlberg, Jean-Nicolas Lang, Mathieu Pellen Categories: hep-ph hep-ex Comments: 17 pages, 4 figures \\ Theoretical predictions with next-to-next-to-leading order (NNLO) QCD accuracy combined with the next-to-leading order (NLO) electroweak (EW) corrections are presented for differential observables of the double-Higgs production process via vector-boson fusion. While the QCD corrections were previously known, the EW ones are computed here for the first time. The numerical results are obtained for a realistic experimental set-up at the LHC and are presented in the form of fiducial cross sections and differential distributions. Within this setup we find that the VBF approximation employed in the NNLO QCD correction is accurate at the sub-percent level. We find that the NLO EW corrections within the fiducial volume are $-6.1\%$, making them of almost the same order as the NLO QCD corrections. In some kinematic regions they can grow as large as $-30\%$ making them the dominant radiative corrections. When the EW corrections are combined with the NNLO QCD corrections we find a total correction of $-14.8\%$. The results presented here thus comprise the state-of-the-art theoretical predicition for the double-Higgs production via vector-boson fusion, which will be of value to the high-luminosity programme at the LHC. \\ ( https://arxiv.org/abs/2005.13341 , 171kb) ------------------------------------------------------------------------------ \\ arXiv:2005.13384 Date: Wed, 27 May 2020 14:28:24 GMT (447kb,D) Title: Dark Matter-Neutrino Interconversion at COHERENT, Direct Detection, and the Early Universe Authors: Nicholas Hurtado, Hana Mir, Ian M. Shoemaker, Eli Welch, and Jason Wyenberg Categories: hep-ph astro-ph.CO hep-ex Comments: 7 pages, 5 figures \\ We study a Dark Matter (DM) model in which the dominant coupling to the standard model occurs through a neutrino-DM-scalar coupling. The new singlet scalar will generically have couplings to nuclei/electrons arising from renormalizable Higgs portal interactions. As a result the DM particle $X$ can convert into a neutrino via scattering on a target nucleus $\mathcal{N}$: $ X + \mathcal{N} \rightarrow \nu + \mathcal{N}$, leading to striking signatures at direct detection experiments. Similarly, DM can be produced in neutrino scattering events at neutrino experiments: $ \nu + \mathcal{N} \rightarrow X + \mathcal{N}$, predicting spectral distortions at experiments such as COHERENT. Furthermore, the model allows for late kinetic decoupling of dark matter with implications for small-scale structure. At low masses, we find that COHERENT and late kinetic decoupling produce the strongest constraints on the model, while at high masses the leading constraints come from DM down-scattering at XENON1T and Borexino. Future improvement will come from CE$\nu$NS data, ultra-low threshold direct detection, and rare kaon decays. \\ ( https://arxiv.org/abs/2005.13384 , 447kb) ------------------------------------------------------------------------------ \\ arXiv:2005.13443 Date: Wed, 27 May 2020 15:54:29 GMT (464kb,D) Title: Light Dark Matter in a minimal extension with two additional real singlets Authors: Markos Maniatis Categories: hep-ph Comments: 14 pages, 4 figures \\ The direct searches for heavy scalar Dark Matter with a mass of order 100 GeV are much more sensitive than for light Dark Matter of order 1 GeV. The question arises whether Dark Matter could be light and has escaped detection so far. We study a simple extension of the Standard Model with two additional real singlets. We show that this simple extension may provide the observed relic Dark Matter density, does not disturb Big-Bang nucleosynthesis nor the Cosmic Microwave Radiation observations and fulfills the conditions of clumping behavior for different sizes of Galaxies. The potential of one Standard Model-like Higgs-boson doublet and the two singlets gives rise to a changed Higgs phenomenology, in particular, an enhanced invisible Higgs-boson decay rate is expected, detectable by missing transversal momentum searches at the ATLAS and CMS experiments at CERN. \\ ( https://arxiv.org/abs/2005.13443 , 464kb) ------------------------------------------------------------------------------ \\ arXiv:2005.13518 Date: Wed, 27 May 2020 17:51:19 GMT (23kb) Title: Extending Trinity to the Scalar Sector through Discrete Flavoured Symmetries Authors: Jo\~ao M. Alves, Francisco J. Botella, Gustavo C. Branco and Miguel Nebot Categories: hep-ph Comments: 24 pages \\ We conjecture the existence of a relation between elementary scalars and fermions, making it plausible the existence of three Higgs doublets. We introduce a Trinity Principle (TP) which, given the fact that there are no massless quarks, requires the existence of a minimum of three Higgs doublets. The TP states that each line of the mass matrix of a quark of a given charge should receive the contribution from one and only one scalar doublet and furthermore a given scalar doublet should contribute to one and only one line of the mass matrix of a quark of a given charge. This principle is analogous to the Natural Flavour Conservation (NFC) of Glashow and Weinberg with the key distinction that NFC required the introduction of a flavour blind symmetry, while the TP requires a flavoured symmetry, to be implemented in a natural way. We provide two examples which satisfy the Trinity Principle based on $\mathbb{Z}_3$ and $\mathbb{Z}_2\times\mathbb{Z}_2'$ flavoured symmetries, and show that they are the minimal multi-Higgs extensions of the Standard Model where CP can be imposed as a symmetry of the full Lagrangian and broken by the vacuum, without requiring soft-breaking terms. We show that the vacuum phases are sufficient to generate a complex CKM matrix, in agreement with experiment. The above mentioned flavoured symmetries lead to a strong reduction in the number of parameters in the Yukawa interactions, enabling a control of the Scalar Flavour Changing Neutral Couplings (SFCNC). We analyse some of the other physical implications of the two models, including an estimate of the enhancement of the Baryon Asymmetry of the Universe provided by the new sources of CP violation, and a discussion of the the strength of their tree-level SFCNC. \\ ( https://arxiv.org/abs/2005.13518 , 23kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:1902.00783 (*cross-listing*) Date: Sat, 2 Feb 2019 20:37:37 GMT (10kb) Title: General Modified Friedmann Equations in Rainbow Flat Universe, by Thermodynamics Authors: A.

There are $|M|$ zero-modes on $T^2$ with the magnetic flux $M$. Their wavefunctions as well as massive modes behave as modular forms of weight $1/2$ and represent the double covering group of $\Gamma \equiv SL(2,\mathbb{Z})$, $\widetilde{\Gamma} \equiv \widetilde{SL}(2,\mathbb{Z})$. Each wavefunction on $T^2$ with the magnetic flux $M$ transforms under $\widetilde{\Gamma}(2|M|)$, which is the normal subgroup of $\widetilde{SL}(2,\mathbb{Z})$. Then, $|M|$ zero-modes are representations of the quotient group $\widetilde{\Gamma}'_{2|M|} \equiv \widetilde{\Gamma}/\widetilde{\Gamma}(2|M|)$. We also study the modular symmetry on twisted and shifted orbifolds $T^2/\mathbb{Z}_N$. Wavefunctions are decomposed into smaller representations by eigenvalues of twist and shift. They provide us with reduction of reducible representations on $T^2$. \\ ( https://arxiv.org/abs/2005.12642 , 25kb) ------------------------------------------------------------------------------ \\ arXiv:2005.12930 (*cross-listing*) Date: Tue, 26 May 2020 18:00:05 GMT (399kb,D) Title: New de Sitter solutions of 10d type IIB supergravity Authors: David Andriot, Paul Marconnet, Timm Wrase Categories: hep-th gr-qc hep-ph Comments: 28 pages + appendices \\ We find and study 17 new de Sitter solutions of ten-dimensional (10d) type IIB supergravity with intersecting D5-branes and orientifold O5-planes, as well as a new Minkowski one.

To examine the in-medium properties of such light clusters, we consider a much simplified system in which like an impurity, a single alpha particle is embedded in a zero-temperature, dilute gas of non-interacting neutrons. By adopting a non-selfconsistent ladder approximation for the effective interaction between the impurity and the gas, which is often used for analyses of Fermi polarons in a gas of ultracold atoms, we calculate the quasiparticle properties of the impurity, i.e., the energy shift, effective mass, quasiparticle residue, and damping rate. \\ ( https://arxiv.org/abs/2005.13196 , 22kb) ------------------------------------------------------------------------------ \\ arXiv:2005.13233 (*cross-listing*) Date: Wed, 27 May 2020 08:30:38 GMT (11kb) Title: Conserved charges in general relativity Authors: Sinya Aoki, Tetsuya Onogi, Shuichi Yokoyama Categories: gr-qc hep-ph hep-th nucl-th Comments: 5 pages Report-no: YITP-20-59, OU-HET-1056 \\ We present a precise definition of a conserved quantity from an arbitrary covariantly conserved current available in a general curved spacetime.

As a byproduct we show that the definition leads to a correction to the known mass formula of a compact star in the Oppenheimer-Volkoff equation.
