What is Testing the Phase Transition Parameters Inside Neutron Stars with the Production of Protons and Lambdas in Relativistic Heavy-ion Collisions about?
We demonstrate the consistency of the quark deconfinement phase transition parameters in the betastable neutron star matter and in the nearly symmetric nuclear matter formed in heavy-ion collisions (HICs). We investigate the proton and Λ flow in Au þ Au collisions at 3 and 4.5 GeV=nucleon incident beam energies with the pure hadron cascade version of a multiphase transport model. The phase transition in HICs and neutron stars is described based on a class of hybrid equations of state from the quark meanfield model for the hadronic phase and a constant-speed-of-sound parametrization for the high-density quark phase. The measurements of the anisotropic proton flow at 3 GeV=nucleon by the STAR Collaboration favor a relatively low phase transition density lower than ∼2.5 times saturation density indicated by the gravitational wave and electromagnetic observations of neutron stars. And the proton flow data at the higher energy of 4.5 GeV=nucleon can be used to effectively constrain the softness of highdensity quark matter equations of state. Finally, compared to the proton flow, the Λ flow is found to be less sensitive and not constraining to the equations of state.
