Open and Hidden Strangeness with Kaons and φ-Mesons in Bjorken Energy Density Approach for Central Collisions from SPS to LHC
Abstract
We use the available data on $$\left\langle {{{dN} \mathord{\left/ {\vphantom {{dN} {dy}}} \right. \kern-0em} {dy}}} \right\rangle $$ and $$\left\langle {{{p}_{{\text{T}}}}} \right\rangle $$ for the identified hadrons including $${{\pi }^{ + }}$$+ $${{\pi }^{ - }}$$, $${{K}^{ + }}$$ + $${{K}^{ - }}$$, $$p$$ + $$\bar {p}$$, $$K{\text{*}}{{(892)}^{0}}$$, $$\overline K {\text{*}}{{(892)}^{0}}$$ and φ-mesons, registered at midrapidity $$(\left| y \right| < 0.5)$$ in 0-5% central Au + Au, Pb + Pb and Xe + Xe collisions in a broad range of energies. The goal is to compare the relative contributions to the Bjorken energy density. Particles, like strangeness-neutral φ-meson (a system of $$s\bar {s}$$ 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.
