论文摘要
我们将天线减法方法扩展到将强子碎片过程包括在$ e^+e^ - $ collisions中的QCD中的近代到领先顺序（NNLO）。为了处理与碎片化过程相关的共线奇异性，我们引入了与相关的相空间映射的最终最终运动学中的碎片化天线功能。这些天线函数在相关的相位空间上进行了整合，从而保留了它们对碎片部分动量分数的依赖。对已知的NNLO系数函数进行了对积分的天线函数的交叉检查。
We extend the antenna subtraction method to include hadron fragmentation processes up to next-to-next-to-leading order (NNLO) in QCD in $e^+e^-$ collisions. To handle collinear singularities associated with the fragmentation process, we introduce fragmentation antenna functions in final-final kinematics with associated phase space mappings. These antenna functions are integrated over the relevant phase spaces, retaining their dependence on the momentum fraction of the fragmenting parton. The integrated antenna functions are cross-checked against the known NNLO coefficient functions for identified hadron production from $γ^*/Z^* \to q\bar{q}$ and $H \to gg$ processes.
