粲夸克与QCD状态方程

Charm Quarks and the QCD Equation of State

Michael Cheng

摘要:

本文利用动力学产生的2+1味背景和零化学势条件下部分猝灭的p4粲夸克研究了粲夸克对QCD状态方程的影响。我们给出了在高温区($T_c < T < 4 T_c$)的能量密度和压力的粲夸克贡献的初步结果,并将其与自由场计算进行比较。粲夸克的质量是通过测量粲偶素谱来确定的。

英文摘要:

We present a study of the effect of charm quarks on the QCD equation of state using partially-quenched p4 charm quarks on a dynamically generated 2+1 flavor background, at zero chemical potential. We show preliminary results for the charm quark contribution to the energy density and pressure in the high temperature region ($T_c < T < 4 T_c$) and compare it to the free-field calculation. The charm quark mass is determined by measuring the charmonium spectrum.
