The transverse momentum ($p_{\mathrm{T}}$) distributions of K$^{*}(892)^{0}$ and $\phi(1020)$ mesons have been measured at midrapidity $(|y|<0.5)$ up to $p_{\mathrm{T}} = 20$ GeV$/c$ in inelastic pp collisions and for several Pb-Pb collision centralities. The collision centrality and collision energy dependence of the average transverse momenta agree with the radial flow scenario observed with stable hadrons, showing that the effect is stronger for more central collisions and higher collision energies. The $\mathrm{K^{*0}/K}$ ratio is found to be suppressed in Pb-Pb collisions relative to pp collisions: this indicates a loss of the measured K$^{*}(892)^{0}$ signal due to rescattering of its decay products in the hadronic phase. In contrast, for the longer-lived $\phi(1020)$ mesons, no such suppression is observed. The nuclear modification factors ($R_{\rm AA}$) of K$^{*}(892)^{0}$ and $\phi(1020)$ mesons are calculated using pp reference spectra at the same collision energy. In central Pb-Pb collisions for $p_{\rm T} > 8$ GeV$/c$, the $R_{\rm AA}$ values of K$^{*}(892)^{0}$ and $\phi(1020)$ are below unity and observed to be similar to those of pions, kaons, and (anti)protons. The $R_{\rm AA}$ values at high $p_{\mathrm T}$ for K$^{*}(892)^{0}$ and $\phi(1020)$ mesons are in agreement within uncertainties for $\sqrt{s_\mathrm{NN}} = 5.02$ and 2.76 TeV. \\ ( https://arxiv.org/abs/2106.13113 , 264kb) %-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%- ------------------------------------------------------------------------------ \\ arXiv:2106.12922 (*cross-listing*) Date: Thu, 24 Jun 2021 11:24:35 GMT (436kb) Title: Electroweak Physics: Summary Authors: Rupa Chatterjee Categories: nucl-th nucl-ex Comments: 9 pages, 3 figures, Electroweak Physics: Summary, 10th International Conference on Hard and Electromagnetic Probes of High-Energy Nuclear Collisions (Hard Probes 2020) \\ Electroweak probes are potential tool to study the properties of the hot and dense strongly interacting matter produced in relativistic nuclear collisions due to their unique nature. A selection of the new experimental analysis and results from theory calculations on electromagnetic and weak probes presented at the Hard Probes 2020 are discussed in this contribution. \\ ( https://arxiv.org/abs/2106.12922 , 436kb) ------------------------------------------------------------------------------ \\ arXiv:2106.12988 (*cross-listing*) Date: Tue, 22 Jun 2021 21:37:02 GMT (594kb) Title: Enhanced D-D Fusion Rates when the Coulomb Barrier Is Lowered by Electrons Authors: Alfred Y. Wong, Alexander Gunn, Allan X. Chen, Chun-Ching Shih, Mason J. Guffey Categories: physics.plasm-ph nucl-ex Comments: 19 pages, 7 figures \\ A profusion of unbound, low-energy electrons creates a local electric field that reduces Coulomb potential and increases quantum tunneling probability for pairs of nuclei. Neutral beam-target experiments on deuterium-deuterium fusion reactions, observed with neutron detectors, show percentage increases in fusion products are consistent with electron-screening predictions from Schrodinger wave mechanics. Experiments performed confirm that observed fusion rate enhancement with a negatively biased target is primarily due to changes to the fusion cross section, rather than simply acceleration due to electrostatic forces. \\ ( https://arxiv.org/abs/2106.12988 , 594kb) %%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%%--%% ------------------------------------------------------------------------------ \\ arXiv:2001.04201 replaced with revised version Thu, 24 Jun 2021 08:02:43 GMT (431kb,D) Title: Longitudinal flow decorrelations in Xe+Xe collisions at $\sqrt{s_{\mathrm{NN}}}=5.44$ TeV with the ATLAS detector Authors: ATLAS Collaboration Categories: nucl-ex hep-ex Comments: 29 pages in total, author list starting page 13, 4 figures.
