A Bjorken sum rule for semileptonic ${\Omega }_b$ decays to ground and excited charmed baryon states

Abstract

We derive a Bjorken sum rule for semileptonic ${\Omega }_b$ decays to ground and low-lying negative-parity excited charmed baryon states, in the heavy quark limit. We discuss the restriction from this sum rule on form factors and compare it with some models.
