Abstract

We present the calculation of the spectrum of baryons containing one heavy quark. Heavy baryon and meson mass splittings are computed and compared with experiment. We give preliminary results for the form factor $G_1$ for the semileptonic decay $ \Lambda_b \rightarrow \Lambda_c l \bar{\nu} $ and investigate its flavour symmetry.
