摘要：

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 less-than-or-equal-to 9 terms of the OPE. Sum rules for heavy baryons LAMBDA(Q) and SIGMA(G)(*) are analysed.
