Effective lagrangian for B and D semileptonic decays
Abstract
Description
An effective lagrangian incorporating both chiral and heavy quark symmetries and describing the low momentum interactions of heavy mesons and light scalar and vector resonances is presented. Using some available data and assuming nearest pole dominance for the form factors we can calculate, at the leading order in chiral and heavy quark expansion, semileptonic $B$ and $D$ decays into light mesons.
