Open and hidden strangeness with kaons and $φ$-mesons in Bjorken energy density approach for central A+A collisions from SPS to LHC

Abstract

We use the available data on $ $ and $<\it{p}_T>$ for the identified hadrons including $π^{+}+π^{-}$, $K^{+}+K^{-}$, $p+\overline{p}$, $K^*(892)^0$ and $φ$-mesons, registered at midrapidity ($\vert y\vert < 0.5)$ in central 0-5% Au-Au, Pb-Pb and Xe+Xe collisions in a broad range of energies in order to compare the relative contributions to the Bjorken energy density. Particles, like strangeness-neutral $φ$-meson (a system of $s\overline{s})$ quarks) and K-meson (containing single s-quark), are of specific interest because they might have different production mechanisms and differ in sensitivity to the properties of the QGP-medium formed in relativistic heavy-ion collisions.
