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, $f_{\pi^+_5}$ and $f_{K^+_5}$ . We consider the partially quenched, ``full QCD'' (with three dynamical flavors), and quenched cases.
