Abstract

We present analytical next-to-leading order results for the correlator of b aryonic currents at the three-loop level with one finite mass quark. We obt ain the massless and the HQET limit of the correlator from the general form ula as particular cases. We also give explicit expressions for the moments of the spectral density.
