Abstract:Light (anti-)nuclei in relativistic heavy-ion collisions are considered to be formed by the coalescence mechanism of (anti-)nucleons in the present work. Using a dynamical phase-space coalescence model coupled with a multi-phase transport (AMPT) model, we explore the formation of light clusters such as deuteron, triton and their anti-particles in different centralities for 197 Au + 197 Au collisions at √ sNN = 39 GeV. The calculated transverse momentum spectra of protons, deuterons, and tritons are comparable… Show more
