扭曲质量费米子算符的真空期望值
Vacuum Expectation Values of Twisted Mass Fermion Operators
摘要：
在猝灭的$20^3 \times 32$格点$β=6.0$上用噪声方法研究了Wilson和扭曲质量标量和赝标量不连通环算符之间的真空期望值和相对线性相关.我们在$κ$，$μ$参数空间中的最大扭曲线附近显示结果，定义为没有宇称混合或PCAC夸克质量消失。
英文摘要：
Using noise methods on a quenched $20^3 \times 32$ lattice at $β=6.0$, we have investigated vacuum expectation values and relative linear correlations among the various Wilson and twisted mass scalar and pseudoscalar disconnected loop operators. We show results near the maximal twist lines in $κ$, $μ$ parameter space, either defined as the absence of parity mixing or the vanishing of the PCAC quark mass.
