A new form of QCD coherence for multiple soft emissions using Glauber-SCET
Abstract Amplitude-level factorization for a soft gluon emission has long been understood in terms of a product of loop-expanded soft-gluon currents and hard scattering matrix elements, both of which are infrared (IR) divergent. Thus, the amplitude for multiple soft gluon emissions, ordered in their...
