论文摘要
我们计算$ {\ cal o}（α_s^3）$ double-eal-virtual（rrv）和double-Virtual-real（VVR）软贡献对推力/零杰特斯事件形状的软贡献。结果清除了通往完整$ {\ cal o}（α_s^3）$推力软功能的最顽固的障碍之一。 The results presented here serve as the key input to realize the next-to-next-to-next-to-leading logarithmic prime (N${}^3$LL') % and even the next-to-next-to-next-to-next-to-leading logarithmic (N${}^4$LL) resummation of the thrust event shape.获得的结果还构成了$ n $ jettiness-subtraction方案的重要成分，该方案在近代到接头订单（n $ {}^3 $ lo）。
We compute the ${\cal O}(α_s^3)$ 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 ${\cal O}(α_s^3)$ thrust soft function. The results presented here serve as the key input to realize the next-to-next-to-next-to-leading logarithmic prime (N${}^3$LL') % and even the next-to-next-to-next-to-next-to-leading logarithmic (N${}^4$LL) resummation of the thrust event shape. The obtained results also constitute the important ingredients of the $N$-jettiness-subtraction scheme at next-to-next-to-next-to-leading order (N${}^3$LO).
