The first measurements of anisotropic flow coefficients for vn mid-rapidity charged particles in Xe–Xe collisions at √sNN=5.44 TeV are presented. Comparing these measurements to those from Pb–Pb collisions at √sNN=5.02 TeV, v2 is found to be suppressed for mid-central collisions at the same centrality, and enhanced for central collisions. The values of v3 are generally larger in Xe–Xe than in Pb–Pb at a given centrality. These observations are consistent with expectations from hydrodynamic predictions. When both and are divided by their corresponding eccentricities for a variety of initial state models, they generally scale with transverse density when comparing Xe–Xe and Pb–Pb, with some deviations observed in central Xe–Xe and Pb–Pb collisions. These results assist in placing strong constraints on both the initial state geometry and medium response for relativistic heavy-ion collisions.

Diffusion processes involving multiple conserved charges : a study from kinetic theory and implications to the fluid-dynamical modeling of heavy ion collisions
Fotakis, Jan A.; Greif, Moritz; Greiner, Carsten; Denicol, Gabriel S.; Niemi, Harri (American Physical Society, 2020)The bulk nuclear matter produced in heavy ion collisions carries a multitude of conserved quantum numbers: electric charge, baryon number, and strangeness. Therefore, the diffusion processes associated with these conserved ... -
Nucleon dissociation and incoherent J/ψ photoproduction on nuclei in ion ultraperipheral collisions at the CERN Large Hadron Collider
Guzey, Vadim; Strikman, M.; Zhalov, M. (American Physical Society, 2019)Using the general notion of cross section fluctuations in hadron-nucleus scattering at high energies, we derive an expression for the cross section of incoherent J / ψ photoproduction on heavy nuclei d σ γ A ... -
ϕ meson production in p+Al, p+Au, d+Au, and 3He+Au collisions at √sNN = 200 GeV
PHENIX Collaboration (American Physical Society (APS), 2022)Small nuclear collisions are mainly sensitive to cold-nuclear-matter effects; however, the collective behavior observed in these collisions shows a hint of hot-nuclear-matter effects. The identified-particle spectra, ... -
ψ(2S) suppression in Pb-Pb collisions at the LHC
ALICE collaboration (American Physical Society (APS), 2024)The production of the ψ(2S) charmonium state was measured with ALICE in Pb-Pb collisions at √sNN=5.02 TeV, in the dimuon decay channel. A significant signal was observed for the first time at LHC energies down to zero ... -
Effects of nuclear structure and quantum interference on diffractive vector meson production in ultraperipheral nuclear collisions
Mäntysaari, Heikki; Salazar, Farid; Schenke, Björn; Shen, Chun; Zhao, Wenbin (American Physical Society (APS), 2024)We study diffractive vector meson production in ultraperipheral collisions of heavy nuclei, utilizing a theoretical framework based on the color glass condensate formalism. We focus on Au + Au, U + U, Ru + Ru, Zr + Zr, and ...
