Strangeness enhancement at LHC
Johann Rafelski (Arizona), and Jean Letessier (Arizona and, Paris-LPTHE)
TL;DR
This paper investigates strangeness production in the quark-gluon plasma at LHC, comparing equilibrium and non-equilibrium conditions to identify key experimental signatures of the hot QGP fireball.
Contribution
It provides a detailed analysis of strangeness enhancement and proposes observable differences between equilibrium and non-equilibrium scenarios at LHC.
Findings
Strangeness yields are sensitive to the QGP conditions.
Chemical non-equilibrium models better fit the observed data.
Identifies specific experimental signatures of strangeness enhancement.
Abstract
We study production of strangeness in the hot QGP fireball in conditions achieved at LHC, and use these results to obtain soft (strange) hadron multiplicities. We compare the chemical equilibrium and non-equilibrium conditions and identify characteristic experimental observables.
