We extend a semi-analytical model that includes the finite nuclear thickness to calculate the energy density (t) and conserved-charge densities including the net-baryon density nB(t) produced at mid-pseudorapidity in central Au+Au collisions at different energies. Assuming the formation of an equilibrated quark-gluon plasma with either quantum statistics or Boltzmann statistics, we extract the temperature T and chemical potentials μB, μS and μQ as functions of time. This then allows us to semi-analytically calculate the T − μB trajectory of relativistic nuclear collisions in the QCD phase diagram, which should benefit the studies of high density physics including the search for the critical end point. This model is also useful for exploring the trajectories in the more general QCD phase diagram in the T − μB − μS − μQ space. ∗Electronic address: [e-mail] †Electronic address: [e-mail] 1 ar X iv :2 11 1. 13 93 2v 1 [ nu cl -t h] 2 7 N ov 2 02 1
