The Equation of State and Multiparticle Production
R. N. Rogalyov
TL;DR
This paper examines particle distributions in heavy-ion collisions, highlighting limitations of existing models and proposing the net-baryon number freezeout temperature and sea quarks as key factors in understanding observed fluctuations.
Contribution
It introduces the concept of net-baryon number freezeout temperature and emphasizes the role of sea quarks in fluctuations, challenging existing models.
Findings
Neither FQM nor HRG models fully explain LHC data.
Net-baryon number freezeout temperature is a relevant concept.
Sea quarks may significantly contribute to fluctuations.
Abstract
We discuss the distribution of fireballs produced in heavy-ion collisions in the net-baryon number and argue that neither the Free-Quark Model (FQM) nor the Hadron Resonance Gas (HRG) model can provide a comprehensive explanation of the distribution observed at the LHC. The concept of net-baryon number freezeout temperature is suggested and the role of sea quarks as a possible source of net-baryon number fluctuations is emphasized.
