Chiral symmetry and many-body nonleptonic decays of bottom hadrons

Abstract

Chiral symmetry can be applied to many-body nonleptonic decays of heavy hadrons. We establish the chiral effective Hamiltonian for some typical many-body nonleptonic decays of bottom hadrons. We discuss the lowest-order contributions coming from such a Hamiltonian and present, as an example, a calculation of decay distributions of $B^{-}\to D^{+}{D}_s^{-}{\pi }^{-}$ and $B^{-}\to D^{\ast +}{D}_s^{-}{\pi }^{-}$. We emphasize that wide applications of this method are possible.
