TTP - TTP09-15 Light quark mass effects in the chromomagnetic moment

Institute for Theoretical Particle Physics (TTP)

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.
