重叠费米子作为价夸克的连续极限标度

Continuum-limit scaling of overlap fermions as valence quarks

Krzysztof Cichy, Gregorio Herdoiza, Karl Jansen

摘要:

我们提出了一个混合行动的方法,采用动态扭曲质量费米子在海洋部门和重叠价费米子,测试连续极限标度行为的物理量的目的,以π衰变常数为例的结果。为了使计算实用,我们为此目的施加一个固定的有限体积与晶格大小$L\approx1.3$ FM。我们还简要回顾了我们用来处理重叠费米子的技术。

英文摘要:

We present the results of a mixed action approach, employing dynamical twisted mass fermions in the sea sector and overlap valence fermions, with the aim of testing the continuum limit scaling behaviour of physical quantities, taking the pion decay constant as an example. To render the computations practical, we impose for this purpose a fixed finite volume with lattice size $L\approx1.3$ fm. We also briefly review the techniques we have used to deal with overlap fermions.
