Light (anti-)nuclei production and flow in relativistic heavy-ion collisions

Abstract

Using the coalescence model based on the phase-space distributions of protons, neutrons, $\mathrm{\ensuremath{\Lambda}}\mathrm{s}$, and their antiparticles from a multiphase transport (AMPT) model, we study the production of light nuclei ($\mathrm{H}$, $\mathrm{H}$, $\mathrm{He}$, $\mathrm{H}$) and their antinuclei in Pb+Pb collisions at $\sqrt{{s}_{NN}}=2.76$ TeV. The resulting transverse momentum spectra, elliptic flows, and coalescence parameters for these nuclei are presented and compared with available experimental data. We also show the constituent number scaled elliptic flows of these nuclei and discuss its implications.
