Title: Longitudinal dynamics and particle production in relativistic nuclear collisions

 
Abstract: In this talk, I will present an improved three-dimensional dynamical initialization model for relativistic heavy-ion collisions, implementing local energy-momentum conservation and baryon charge fluctuations at string junctions. These improvements lead to an excellent description of the charged hadron and net proton rapidity distributions in Au+Au collisions from 7.7 to 200 GeV and Pb+Pb collisions at 8.77 and 17.3 GeV. Based on these results, we quantify the amount of baryon stopping at the initial impact and baryon transport during the hydrodynamic evolution and hadronic scattering phases. The effects of baryon stopping and strangeness neutrality on identified particle yields are quantified as a function of collision energy. We further expand the model description to asymmetric p+Al and (p, d, $^3$He)+Au collisions at the top RHIC energy and p+Pb, Xe+Xe, and Pb+Pb collisions at LHC energies. The particle rapidity distributions in asymmetric collision systems can provide crucial constraints on modeling the early-time longitudinal dynamics.
