Phys. Rev. D 59, 094015 (1999) [7 pages]Spectator effects in heavy quark effective theory at O(1/mQ3)Received 3 August 1998; published 1 April 1999 We complete the one loop renormalization of the HQET Lagrangian at O(1/mQ3) including four fermion operators with two heavy and two light quark fields in the operator basis. It is shown that as a consequence the short distance coefficients of the operators bilinear in the heavy quark field receive nontrivial corrections. © 1999 The American Physical Society URL:
