用畴壁费米子计算夸克数磁化率

Calculating Quark Number Susceptibilities with Domain-Wall Fermions

Prasad Hegde, Frithjof Karsch, Christian Schmidt

摘要:

本文给出了2+1味动力学畴壁系综上不同夸克数和强子可调性的计算结果。我们发现,iso-spin和电荷磁化率是特别适合于确定的转变温度,因为这些量只显示出很小的统计误差。此外,由同位旋和电荷极化率得到的耦合跃迁值与由手征凝聚体得到的耦合跃迁值吻合得很好。

英文摘要:

We present results from calculations of different quark number and hadronic susceptibilities on 2+1-flavor dynamical domain wall ensembles. We find that the iso-spin and electric charge susceptibilities are especially well suited to determine the transition temperature, as these quantities show only small statistical errors. Moreover, the transition values of the coupling obtained from iso-spin and electrical charge susceptibilities are in good agreement with the one obtained from the chiral condensate.
