Abstract

We present a new calculation of the renormalized HQET Lagrangian at order O(1/m_Q²) and discuss the consequences of the BRST invariance of QCD and the reparameterization invariance of HQET. Our result corrects earlier, conflicting calculations and sets the stage for the calculation of the renormalized currents at order O(1/m_Q²).
