====== TTP98-24 Spectator Effects in Heavy Quark Effective Theory at O(1/m_Q^3) ====== We complete the one loop renormalization of the HQET lagrangian at O(1/m_Q^3) 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. |**Christopher Balzereit** | |** Phys. Rev.
