摘要

我们计算了推力/零喷注度事件形状的 ${\cal O}(\alpha_s^3)$ 双实虚(RRV)与双虚实(VVR)软贡献。该结果扫清了通向完整 ${\cal O}(\alpha_s^3)$ 推力软函数的最顽固障碍之一。此处给出的结果作为实现推力事件形状的次次次领头对数_prime_(N ${}^3$ LL') 乃至次次次次领头对数(N ${}^4$ LL) 重求和的关键输入。所得结果也构成了次次次领头阶(N ${}^3$ LO) $N$ -喷注度减除方案的重要组分。

Updated version to simplify the results. Now the complete VRR results are presented by including the $q\bar{q}$ channel. Full agreement was found with a recent calculation in arXiv:2401.05245
