Abstract

The masses of the p-wave excited heavy baryons have been calculated to \ensuremathΛ_QCD/m_Q order using the QCD sum rule method within the framework of heavy quark effective theory. Numerical results for the kinetic energy \ensuremathλ₁ and chromomagnetic interaction \ensuremathλ₂ 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.
