Staggered Chiral Perturbation Theory with Heavy-Light Mesons

Abstract

We merge heavy quark effective theory with staggered chiral perturbation theory to calculate heavy-light (B, D) meson quantities. We present results at NLO for the $B(D)$ meson decay constant in the partially quenched and full QCD cases, and discuss the calculation of the form factors for $B(D)\to \pi (K)\ell \nu$ decays.
