Chiral Symmetry
SU(3) breaking and the pseudoscalar spectrum in multi-taste QCD
Content
Using the Sigma model to explore the lowest order pseudoscalar spectrum with SU(3) breaking, I consider an additional exact "taste" symmetry to mimic species doubling. I find that rooting replicas of a valid approach such as Wilson fermions reproduces the desired physical spectrum. In contrast, extra symmetries of the rooted staggered approach leave spurious states and a flavor dependent taste multiplicity.
