动力学手征改进费米子的本征谱

The eigenvalue spectrum for dynamical Chirally Improved fermions

Martina Joergler, C. B. Lang

摘要:

研究了具有两个质量简并动力学费米子的QCD中Dirac算符的本征值。规范位形是用HMC和所谓的手征改进的费米子作用量得到的。我们比较重叠狄拉克算子的特征值,这些配置与那些为Chirally改进(CI)运营商(研究较早)。随机矩阵理论的结果使我们能够确定手性凝聚体。

英文摘要:

We study the eigenvalues of Dirac operators in QCD with two mass degenerate dynamical fermions. The gauge configurations have been obtained with HMC and the so-called Chirally Improved fermionic action. We compare eigenvalues obtained for the overlap Dirac operator on these configurations with those for the Chirally Improved (CI) operator (studied earlier). Results of Random Matrix Theory allow us to determine the chiral condensate.
