Bottom (70,1-) baryon multiplet

The aim of this paper is to derive systems of equations for the amplitudes for the case of negative parity (70,1-) bottom nonstrange baryons and to calculate the masses of these particles. In order to calculate masses of (70,1-) bottom baryons we use the relativistic quark model. The relativistic three-quark equations of the (70,1-) bottom baryon multiplet are derived in the framework of the dispersion relation technique. The relativistic three-quark equations of the (70,1-) bottom baryon multiplet are derived. The approximate solutions of these equations using the method based on the extraction of leading singularities of the amplitude are obtained. The masses of 21 baryons are predicted.

Charm, bottom, strange baryon masses using QCD sum rules

We use the method of QCD sum rules to estimate the masses of the charm baryon, [Formula: see text], bottom baryon [Formula: see text], strange baryon [Formula: see text] and compare them to their experimental values.
