Absence of Parity-Flavor Breaking Phase in QCD with two Flavors of   Wilson fermions for beta greater than or equal to 5.0
  We present data testing the existence of a parity-flavor breaking phase in simulations of QCD with two flavors of light Wilson fermions. This is done by explicit simulations on lattice sizes of $6^4$, $8^4$ and $10^4$ for a variety of values of $\beta$ and $\kappa$ as well as the coefficient, $h$, of an explicit breaking term included in the action. We find that at $\beta=6/g^2 $ equal to or greater than 5.0 extrapolation in the parameter $h$ as well as in the lattice volume show no indication of a phase where parity and flavor are spontaneously broken in the limit of zero $h$.
