扭曲质量格点量子色动力学

Twisted mass lattice QCD

A. Shindler

摘要:

本文综述了Wilson格点量子色动力学的一种变体:Wilson扭曲质量格点量子色动力学的理论基础、性质以及迄今为止的模拟结果。重点放在离散误差和这些离散误差的影响上的相位结构的威尔逊类费米子的手征极限。在晶格模拟中使用不同的晶格行动的海和价夸克,以减轻唯象相关的本地运营商的重整化模式的可能性,也进行了讨论。

英文摘要:

I review the theoretical foundations, properties as well as the simulation results obtained so far of a variant of the Wilson lattice QCD formulation: Wilson twisted mass lattice QCD. Emphasis is put on the discretization errors and on the effects of these discretization errors on the phase structure for Wilson-like fermions in the chiral limit. The possibility to use in lattice simulations different lattice actions for sea and valence quarks to ease the renormalization patterns of phenomenologically relevant local operators, is also discussed.
