PREDICTING THE MASSES OF BARYONS CONTAINING ONE OR TWO HEAVY QUARKS

Abstract

The Feynman-Hellmann theorem and semiempirical mass formulas are used to predict the masses of baryons containing one or two heavy quarks. In particular, the mass of the ${\Lambda }_b$ is predicted to be $5620\pm 40$ MeV, a value consistent with measurements.
