相互作用强子共振气体与格点量子色动力学的相遇

Interacting hadron resonance gas meets lattice QCD

A. Andronic, P. Braun-Munzinger, J. Stachel, M. Winn

摘要:

本文在相互作用强子共振气体的框架下,给出了一个计算物理量的方法。相互作用是通过修正强子的有限大小来模拟的。我们调查的灵敏度模型计算的强子的半径,这是一个参数的模型。我们对能量、熵密度和压力等物理量的计算与晶格量子色动力学(QCD)形式主义的预测相矛盾。

英文摘要:

We present, in the framework of the interacting hadron resonance gas, an evaluation of thermodynamical quantities. The interaction is modelled via a correction for the finite size of the hadrons. We investigate the sensitivity of the model calculations on the radius of the hadrons, which is a parameter of the model. Our calculations for thermodynamical quantities as energy and entropy densities and pressure are confronted with predictions using the lattice Quantum Chromodynamics (QCD) formalism.
