Baryonic currents and their correlators in the heavy quark effective theory
Description
HQET currents with the quantum numbers of the ground-state baryons are discussed. One-loop anomalous dimensions are calculated, and exact one-loop matching to QCD currents is found. Two-point correlators of these currents are calculated taking into account d≤9 terms of the OPE. Sum rules for heavy baryons ΛQ and ΣQ(*) are analysed. (orig.)
