摘要：

We discuss the renormalization of local, scalar and pseudoscalar dimension-5 operators containing a heavy and a light quark field at scales below the heavy-quark mass, using the formalism of the heavy-quark effective theory (HQET). We calculate the anomalous dimensions of these operators and their mixing to one-loop order. We also perform the one-loop matching of gluon and photon penguin operators onto operators of the HQET. We discuss applications of our results to the mixing of gluon and photon penguin operators at low renormalization scales, and to the calculation of 1/m(Q)(2) corrections to meson decays constants.
