摘要：Using noise methods on a quenched 203 ×32 lattice at b = 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 k, μ parameter space, either defined as the absence of parity mixing or the vanishing of the PCAC quark mass.
