Remarks on strange-quark simulations with Wilson fermions
Daniel Mohler, Stefan Schaefer
Abstract
In the simulation of QCD with $2+1$ flavors of Wilson fermions, the positivity of the fermion determinant is generally assumed. We present evidence that this assumption is in general not justified and discuss the consequences of this finding.
