====== TTP09-15 Light quark mass effects in the chromomagnetic moment ====== We present the three-loop QCD corrections to the quark chromomagnetic moment including two different nonzero masses. This is a necessary ingredient to obtain the corresponding corrections to the chromomagnetic coefficient in the Heavy Quark Effective Theory (HQET) Lagrangian. |**S. Bekavac, A. Grozin, D. Seidel, M.
