Probabilities for different transfer channels are calculated by using particle-number projection method. The results indicate that neutron stripping (transfer from the projectile to the target) and proton pick-up (transfer from the target to the projectile) are favored. Deexcitation of the primary fragments are treated by using the state-of-art statistical code GEMINI++. Primary and final production cross sections of the target-like fragments (with $Z=77$ to $Z=87$) are investigated. The results reveal that fission decay of heavy nuclei plays an important role in the deexcitation process of nuclei with $Z>82$. It is also found that the final production cross sections of neutron-rich (deficient) nuclei slightly (strongly) depend on the incident energy. \\ ( https://arxiv.org/abs/1807.10412 , 237kb) ------------------------------------------------------------------------------ \\ arXiv:1807.10532 Date: Fri, 27 Jul 2018 10:57:55 GMT (32kb) Title: Analysis of the MINERvA antineutrino double-differential cross sections within the SuSAv2-MEC model Authors: G. D. Megias, M. B. Barbaro, J. A. Caballero Categories: nucl-th Comments: 5 pages, 2 figures \\ We compare the results of the SuSAv2 model including meson-exchange currents (MEC) with the recent measurement of the quasielastic-like double differential antineutrino cross section on hydrocarbon performed by the MINERvA Collaboration. The relativistic nature of the model makes it suitable to describe these data, which correspond to a mean beam energy of 3.5 GeV. The model predictions agree well with the data without need of tuning any parameter. The role of longitudinal MEC is non-negligible and improves the agreement with the data. \\ ( https://arxiv.org/abs/1807.10532 , 32kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:1807.10132 (*cross-listing*) Date: Thu, 26 Jul 2018 13:46:25 GMT (22kb) Title: Lorentz transformation of temperature and effective temperature Authors: Hironori Hoshino and Shin Nakamura Categories: hep-th cond-mat.stat-mech gr-qc hep-ph nucl-th Comments: 13 pages, no figures \\ We derive the Lorentz transformation of temperature by using holography. The Lorentz transformation of temperature has been under debate for more than a century, and three different transformations have been proposed. Here we show that the correct transformation is that proposed by Einstein and Planck. We obtain a relativistic thermal distribution function from holography as well. The distribution function is Lorentz invariant and is consistent with the covariant first law of thermodynamics proposed by Einstein and Planck. The same method is applicable to the effective temperature in nonequilibrium steady states. We derive the boost transformation of the effective temperature. This enables us to distinguish the boost effect from the many-body effect in the effective temperature of a test particle dragged in a heat bath. \\ ( https://arxiv.org/abs/1807.10132 , 22kb) ------------------------------------------------------------------------------ \\ arXiv:1807.10337 (*cross-listing*) Date: Thu, 26 Jul 2018 19:41:05 GMT (1554kb,D) Title: Forward Elastic Scattering and Pomeron Models Authors: M. Broilo, E.G.S. Luna, and M.J. Menon Categories: hep-ph nucl-th Comments: 27 pages, 10 figures, 5 tables \\ Recent data from LHC13 by the TOTEM Collaboration have indicated an unexpected decrease in the value of the $\rho$ parameter and a $\sigma_{tot}$ value in agreement with the trend of previous measurements at 7 and 8 TeV. These data at 13 TeV are not simultaneously described by the predictions from Pomeron models selected by the COMPETE Collaboration, but show agreement with the maximal Odderon dominance, as recently demonstrated by Martynov and Nicolescu. Here we present a detailed analysis on the applicability of Pomeron dominance by means of a general class of forward scattering amplitude, consisting of even-under-crossing leading contributions associated with single, double and triple poles in the complex angular momentum plane. We carry out fits to $pp$ and $\bar{p}p$ data in the interval 5 GeV - 13 TeV. The data set comprises all the accelerator data below 7 TeV and we consider two independent ensembles by adding either only the TOTEM data or TOTEM and ATLAS data at the LHC energy region. In the data reductions to each ensemble the uncertainty regions are evaluated with both one and two standard deviation ($\sim$ 68 \% and $\sim$ 95 \% CL, respectively). Besides the general analytic model, we investigate four particular cases of interest, three of them typical of outstanding models in the literature. We conclude that, within the experimental and theoretical uncertainties and both ensembles, the general model and three particular cases are not able to describe the $\sigma_{tot}$ and $\rho$ data at 13 TeV simultaneously. However, if the discrepancies between the TOTEM and ATLAS data are not resolved, one Pomeron model, associated with double and triple poles and with only 7 free parameters, seems not to be excluded by the complete set of experimental information presently available. \\ ( https://arxiv.org/abs/1807.10337 , 1554kb) ------------------------------------------------------------------------------ \\ arXiv:1807.10348 (*cross-listing*) Date: Thu, 26 Jul 2018 20:25:52 GMT (7069kb,D) Title: The Quark-Gluon Vertex and the QCD Infrared Dynamics Authors: O. Oliveira, W. de Paula, T. Frederico, J. P. B. C de Melo Categories: hep-ph hep-lat hep-th nucl-th \\ We solve the Dyson-Schwinger quark equation for the quark-gluon vertex taking for the quark, gluon and ghost propagators the most recent lattice data available in the Landau gauge. In our approach we go beyond the Ball-Chiu type of vertex by including other tensor structures that results on a vertex that is a function of the incoming quark momentum, incoming gluon momentum and the angle between these two momenta. Our calculation takes into account a recently derived normalization for a quark-ghost kernel form factors and also the gluon contribution for the quark-gluon vertex identified on the study of the lattice soft gluon limit of the tree level tensor structure. Our solution for the quark-gluon vertex returns longitudinal quark-gluon vertex form factors that are strongly enhanced at the infrared region and deviate significantly from their tree level results of quark and gluon momentum below 2 GeV. At high momentum the form factors approach their perturbative values. The computed quark-gluon vertex favours kinematical configurations where the quark momentum $p$ and the gluon momentum $q$ are small and parallel. Further, we find that the quark-gluon vertex is dominated by the form factors associated to the tree level vertex $\gamma_\mu$ and to the scalar $2 \, p_\mu + q_\mu$. The higher rank tensor structures provide small contributions to the vertex. \\ ( https://arxiv.org/abs/1807.10348 , 7069kb) ------------------------------------------------------------------------------ \\ arXiv:1807.10429 (*cross-listing*) Date: Fri, 27 Jul 2018 04:11:57 GMT (136kb) Title: Cross Sections for Inelastic 2-to-2 Meson-Meson Scattering Authors: Ting-Ting Wang, Xiao-Ming Xu Categories: hep-ph nucl-th Comments: 32 pages, 12 figures, 4 tables \\ With quark-antiquark annihilation and creation in the first Born approximation, we study the reactions: $K \bar {K} \to K \bar {K}^\ast, ~K \bar{K} \to K^* \bar{K}, ~\pi K \to \pi K^\ast, ~\pi K \to \rho K, ~\pi \pi \to K \bar{K}^\ast, ~\pi \pi \to K^\ast \bar{K}, ~\pi \pi \to K^\ast \bar{K}^\ast, ~\pi \rho \to K \bar{K}, ~\pi \rho \to K^\ast \bar{K}^\ast, ~\rho \rho \to K^\ast \bar{K}^\ast, ~K \bar{K}^\ast \to \rho \rho$, and $K^* \bar{K} \to \rho \rho$. Unpolarized cross sections for the reactions are obtained from transition amplitudes that are composed of mesonic quark-antiquark relative-motion wave functions and the transition potential for quark-antiquark annihilation and creation. From a quark-antiquark potential that is equivalent to the transition potential, we prove that the total spin of the two final mesons may not equal the total spin of the two initial mesons. Based on flavor matrix elements, cross sections for some isospin channels of reactions can be obtained from the other isospin channels of reactions. Remarkable temperature dependence of the cross sections is found. \\ ( https://arxiv.org/abs/1807.10429 , 136kb) ------------------------------------------------------------------------------ \\ arXiv:1807.10499 (*cross-listing*) Date: Fri, 27 Jul 2018 09:01:22 GMT (715kb) Title: $ \boldsymbol{\gamma} $-vibration in $^{198}$Hg Authors: S.

Observed band structures have been interpreted using the theoretical framework of microscopic triaxial projected shell model (TPSM) approach and it is shown that TPSM results are in fair agreement with the observed energies. \\ ( https://arxiv.org/abs/1807.10499 , 715kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:1710.00991 (*cross-listing*) replaced with revised version Thu, 26 Jul 2018 18:31:19 GMT (44kb) Title: New results from a number operator interpretation of the compositeness of bound and resonant states Authors: J.A.
