Charm手性热力学

Chiral Thermodynamics with Charm

Chihiro Sasaki

摘要:

在有限温度下,在包含重夸克对称性的$2+1+1$味有效拉格朗日量内,建立了粲介子的手征热力学方程。手征质量分裂被证明是不太敏感的轻夸克味,归因于潜在的重夸克对称性。因此,手征对称性的恢复在奇异粲介子中比在奇异轻介子中更快,这与手征SU(4)的结果形成了鲜明的对比。我们还显示了手性交叉周围的轻和重口味之间的相关性。

英文摘要:

Chiral thermodynamics of charmed mesons is formulated at finite temperature within a $2+1+1$-flavored effective Lagrangian incorporating heavy quark symmetry. The chiral mass splittings are shown to be less sensitive to the light-quark flavors, attributed to the underlying heavy quark symmetry. Consequently, chiral symmetry restoration is more accelerated in the strange charmed-mesons than in the strange light mesons, and this is in striking contrast to the chiral SU(4) result. We also show the correlations between light and heavy flavors around the chiral crossover.
