Beauty-Conserving Strangeness-Changing two-body hadronic decays of beauty baryons

摘要

The beauty-conserving strangeness-changing two-body hadronic decays of beauty baryons are examined. Unlike in charm sector where the heavy flavor conserving but strangeness-changing decays are Cabibbo suppressed, in the b-sector they are CKM allowed. The numerical estimates for decay widths of some of the modes are presented in current algebra approach, factorization and quark diagram approach.
