摘要

我们讨论了重离子碰撞中产生的火球在净重子数上的分布，并认为自由夸克模型（FQM）和强子共振气体模型（HRG）都不能全面解释在大型强子对撞机上观测到的分布。提出了净重子数冻结温度的概念，并强调了海夸克作为净重子数波动可能来源的作用。

The Equation of State and Multiparticle Production

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.

期刊介绍： The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
