Extracting strange quark freeze-out information in Pb+Pb collisions at $\sqrt{s_{NN}}$=2.76 TeV from $\varphi$ and $\Omega$ production

Jie Pu, Kai-Jia Sun, Lie-Wen Chen

Using a covariant quark coalescence model combined with a blast-wave-like analytical parametrization for (anti-)strange quark phase-space freeze-out configuration, we extract infor…
