Vacuum Expectation Values of Twisted Mass Fermion Operators

Presenter: Walter Wilcox — Baylor University

Abdou Abdel-Rehim, Walter Wilcox and Randy Lewis

Using noise methods on a quenched 203 32 lattice, we have investigated vacuum expectation values and relative linear correlations among the various Wilson and twisted mass scalar and pseudoscalar operators. We show results near the maximal twist line in κ, parameter space, either defined as the absence of parity mixing or the vanishing of the PCAC quark mass.
