论文摘要
大型强子对撞机（LHC）能量的高质量质子 - 质子（PP）碰撞创造了一个新的研究领域，以寻找在这些事件中可能形成Quark-Gluon等离子体的形成。在本文中，我们使用热力学上一致的tsallis分布函数估计了LHC能量下PP碰撞中形成的物质的各种热性能，例如平均自由路径，同等膨胀性，热压和热容量。研究了粒子物种依赖的平均自由路径和同质体膨胀性，作为最终状态带电粒子多重性的功能，用于在质量中心能量$ \ sqrt {s} $ = 7 tev处的pp碰撞。研究了非延伸性，重化势和温度对这些热性能的影响。将发现与理论期望进行了比较。
High-multiplicity proton-proton (pp) collisions at the Large Hadron Collider (LHC) energies have created a new domain of research to look for a possible formation of quark-gluon plasma in these events. In this paper, we estimate various thermal properties of the matter formed in pp collisions at the LHC energies, such as mean free path, isobaric expansivity, thermal pressure, and heat capacity using a thermodynamically consistent Tsallis distribution function. Particle species-dependent mean free path and isobaric expansivity are studied as functions of final state charged particle multiplicity for pp collisions at the center-of-mass energy $\sqrt{s}$ = 7 TeV. The effects of degree of non-extensivity, baryochemical potential, and temperature on these thermal properties are studied. The findings are compared with the theoretical expectations.
