Heavy Baryons and QCD Sum Rules

Abstract

We discuss an application of QCD sum rules to the heavy baryons ${\Lambda }_Q$ and ${\Sigma }_Q$. The predictions for the masses of heavy baryons, residues and Isgur-Wise function are presented. The new results on two loop anomalous dimensions of baryonic currents and QCD radiative corrections (two- and three- loop contributions) to the first two Wilson coefficients in OPE are explicitly presented.
