Spectator Effects in Heavy Quark Effective Theory at O(1/mQ3)
Abstract
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.
