====== TTP07-14 Three-Loop Chromomagnetic Interaction in HQET ====== We compute the three-loop QCD corrections to the quark chromomagnetic moment and thus obtain the matching coefficient and the anomalous dimension of the chromomagnetic interaction in HQET. As a byproduct we obtain the three-loop corrections to the quark anomalous magnetic moment. |**A.G. Grozin, P. Marquard, J.H. Piclum, M.
