摘要：

We investigate the 1/m corrections to the heavy quark effective theory, where m is the mass of a heavy quark. At this order new flavor conserving operators arise from the expansion of the kinetic energy in the full theory. Along with 1/m corrections to the matching conditions, these operators induce corrections of order LAMBDA-QCD/m to the flavor changing currents which mediate weak decays in the effective theory. We illustrate the calculation of the anomalous dimension matrix for such operators.
