用Wilson夸克修正Banks-Casher关系

Corrections to the Banks-Casher relation with Wilson quarks

S. Necco, A. Shindler

摘要:

Banks-Casher关系将狄拉克算子的谱密度与手征凝聚体的存在和手征对称性的自发破缺联系起来。这个关系式从夸克质量的有限值、有限的时空体积以及(如果在离散晶格上计算的话)晶格间距a的有限值中得到修正。我们提出了一个状态报告,确定这些修正威尔逊夸克。

英文摘要:

The Banks-Casher relation links the spectral density of the Dirac operator with the existence of a chiral condensate and spontaneous breaking of chiral symmetry. This relation receives corrections from a finite value of the quark mass, a finite space-time volume and, if evaluated on a discrete lattice, from the finite value of the lattice spacing a. We present a status report of a determination of these corrections for Wilson quarks.
