We discuss how to construct a simple and easy-To-use helicity operator basis in Soft-Collinear Effective Theory (SCET), for which the hard Wilson coefficients from matching QCD onto SCET are directly given in terms of the color-ordered QCD helicity amplitudes. This provides an interface to seamlessly combine fixed-order helicity amplitudes, which are the basic building blocks of state-of-The-Art next-To-leading order calculations for multileg processes, with a resummation of higher-order logarithmic corrections using SCET.
