天线相减法处理喷流观测量高阶修正中的真实的辐射贡献。该方法是基于天线功能，封装一对硬辐射体部分子之间的所有未解决的辐射。应用这种方法计算强子对撞机的可观测量，初始-初始天线功能与两个辐射在初始状态是必需的。为了将天线减法推广到强子对撞机的次-次-首阶（NNLO）计算，我们导出了单圈初-初天线函数的非积分和积分形式。
A bstractThe antenna subtraction method handles real radiation contributions in higher order corrections to jet observables. The method is based on antenna functions, which encapsulate all unresolved radiation between a pair of hard radiator partons. To apply this method to compute hadron collider observables, initial-initial antenna functions with both radiators in the initial state are required. In view of extending the antenna subtraction method to next-to-next-to-leading order (NNLO) calculations at hadron colliders, we derive the one-loop initial-initial antenna functions in unintegrated and integrated form.
