Abstract
© Copyright EPLA, 2016. The strange-quark occupation factor (γs) is determined from the statistical fit of the multiplicity ratio K+/π+in a wide range of nucleon-nucleon center-of-mass energies (√sNN). From this single-strange-quark subsystem, γs (√sNN) was parametrized as a damped trigonometric functionality and successfully implemented into the hadron resonance gas model, at chemical semiequilibrium. Various particle ratios including K-/π-, Λ-/π-, and Λ-/π-are well reproduced. The phenomenology of γs (√sNN) suggests that the hadrons (γs rises) at √sNN ≃ 7GeV seem to undergo a phase transition to a mixed phase (γs decreases), which is then derived into partons (γ remains unchanged with increasing √sNN), at √sNN ≃ 20 GeV.
