Low Energy Aspects of Heavy Meson Decays

Abstract

I discuss low energy aspects of heavy meson decays, where there is at least one heavy meson in the final state. Examples are $B-\bar{B}$ mixing, $B\to D\bar{D}$, $B\to D{\eta }^{\prime }$, and $B\to D\gamma$. %and $B\to DW$ (Isgur-Wise function). The analysis is performed in the heavy quark limit within heavy-light chiral perturbation theory. Coefficients of $1/N_c$ suppressed chiral Lagrangian terms (beyond factorization) have been estimated by means of a heavy-light chiral quark model.
