A first study of the semi-leptonic decay of the ${\Lambda }_b$ baryon

Abstract

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 $\Lambda$-baryon external states. Its dependence on the heavy and light quark masses is studied. Some result on the semi-leptonic decay ${\Lambda }_b\to {\Lambda }_c+l\nu$ are given.
