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, µ parameter space, either defined as the absence of parity mixing or the vanishing of the PCAC quark mass.
