The renormalization of local dimension-4 operators containing a heavy and a
light quark field at scales below the heavy-quark mass is discussed, using the
formalism of the heavy-quark effective theory. The anomalous dimensions of
these operators and their mixing are calculated to two-loop order. Some
phenomenological applications are briefly discussed.
