Description
I will present a calculation of top quark decay within effective field theory approach at NLO in QCD. The main purpose is to understand how to systematically include QCD corrections to the dimension-six operators. I will focus on two decay channels: 1) t->b+W with W boson in different helicity states, and 2) the flavor changing decay t->c+H. The operator mixing effects will also be discussed.
