The singly bottom baryons are studied in the framework of a nonrelativistic quark model. We use the hypercentral approach to solve the six-dimensional Schrödinger equation of the baryons. Introducing a potential model, the ground state masses of the single-heavy $ \Lambda $ and $ \Sigma $ baryons are calculated. We investigate the $ b \rightarrow c $ semileptonic decay width of the $ \Lambda_{b} $ heavy baryon. Our results are in agreement with the available experimental data and those of other works.
