摘要:

本文介绍了MILC合作组在SU(3)手征拟合下对轻赝标介子扇区的分析情况。该分析包括来自新的星系团的数据,这些星系团具有较小的晶格间距、较小的轻夸克质量和比物理奇异夸克质量更轻的质量。我们的配合物包括NNLO手性异构体。我们目前的结果衰变常数,夸克质量,Gasser-Leutwyler低能常数,并在两个和三个味手征极限凝聚。

英文摘要:

We present the status of the MILC collaboration's analysis of the light pseudoscalar meson sector with SU(3) chiral fits. The analysis includes data from new ensembles with smaller lattice spacing, smaller light quark masses and lighter than physical strange quark masses. Our fits include the NNLO chiral logarithms. We present results for decay constants, quark masses, Gasser-Leutwyler low energy constants, and condensates in the two- and three-flavor chiral limits.
