Non-leptonic beauty baryon decays and -asymmetries based on -Flavor analysis

arXiv:1911.01121 · doi:10.1103/PhysRevD.101.036018

Abstract

We consider hadronic weak decays of beauty-baryons into charmless baryons and pseudoscalar mesons in a general framework based on decomposition of the decay amplitudes. The advantage of the approach lies in the ability to perform an analysis of these decays without any particular set of dynamical assumptions while accounting for the effects of an arbitrarily broken flavor symmetry. Dictated by the symmetries of the effective Hamiltonian that allow us to relate or neglect reduced amplitudes, we derive several sum rule relations between amplitudes and relations between asymmetries in these decays and identify those that hold even if is broken.
