Description
Partially quenched chiral perturbation theory usually assumes that
valence quarks propagating on gauge configurations prepared with sea
quarks of different masses will form a chiral condensate as the
valence quark mass goes to zero. I present a counterexample involving
non-degenerate sea quarks where the valence condensate does not form.
Summary
Partially quenched chiral perturbation theory can fail if the valence quarks are lighter than the average sea quark mass.
