Pseudoscalar Decay Constants in Staggered Chiral Perturbation Theory
Abstract
In a continuation of an ongoing program, we use staggered chiral perturbation theory to calculate the one-loop chiral logarithms and analytic terms in the pseudoscalar meson leptonic decay constants, fπ+5 and fK+5. We consider the partially quenched, ``full QCD'' (with three dynamical flavors), and quenched cases.
