摘要:

本文给出了非零化学势下的QCD状态方程在N_t=6时的新结果,并与N_t=4时的结果进行了比较。我们采用泰勒展开方法,在m_l=0.1 m_s和近似物理奇夸克质量m_s的常物理线上,对2+1类改进的asqtad夸克进行了六阶模拟。

英文摘要:

We present our new results for the QCD equation of state at nonzero chemical potential at N_t=6 and compare them with N_t=4. We use the Taylor expansion method with terms up to sixth order in simulations with 2+1 flavors of improved asqtad quarks along a line of constant physics with m_l=0.1 m_s and approximately physical strange quark mass m_s.
