Abstract

En 中文

We compute the O(alpha(3)(s)) double-real-virtual (RRV) and double-virtual-real (VVR) soft contributions to the thrust/zero-jettiness event shape. The result clears up one of the most stubborn obstacles toward the complete O(alpha(3)(s)) thrust soft function. The results presented here serve the key input to realize the next-to-next-to-next-to-leading logarithmic prime ((NLL)-L-3') resummation of the thrust event shape. The obtained results also constitutes the important ingredients of the N-jettiness-subtraction scheme at next-to-next-to-next-to-leading order ((NLO)-L-3).
