A first study of the semi-leptonic decay of the $Λ_b$ baryon

We present the preliminary results of the first Lattice study of the baryonic Isgur and Wise function obtained from the matrix element of the weak current between $Λ$-baryon external states. Its dependence on the heavy and light quark masses is studied. Some result on the semi-leptonic decay $Λ_b\toΛ_c +lν$ are given.

Heavy Baryon Spectroscopy

We present the preliminary results of an exploratory study of heavy baryon spectroscopy, using the $O(a)$-improved fermionic action. Estimates of masses and splittings at the charm and beauty physical limit are reported.
