Beautiful and other heavy baryons revisited
Abstract
We discuss the mass range for the beautiful baryons λ b, σ b and σ ∗b allowed by rigorous inequalities which are derived in the framework of potential models but have probably a broader domain of validity. We obtain at the same lower bounds on the masses of other baryons. We also compare the numerical prediction of several explicit models. There are convergent indications towards a mass of about 5.6 GeV for the λ b.
