Description
The masses of the p-wave excited heavy baryons have been calculated to ΛQCD/mQ order using the QCD sum rule method within the framework of heavy quark effective theory. Numerical results for the kinetic energy λ1 and chromomagnetic interaction λ2 are presented. The splitting between spin 1/2 and 3/2 doublets derived from our calculation is given; the agreement with the current experiment is good
