摘要

我们提出了在大型强子对撞机上W玻色子与两个光子结合产生的二环螺旋振幅，这些振幅对QCD对W玻色子与两个光子结合产生的邻近到邻近阶QCD预测做出了贡献。我们推导出了前导色极限双回路振幅的紧凑解析表达式，并提供了次前导色贡献的数值结果。我们使用了一个由 NeatIBP 软件包提供的紧凑的逐部分积分等式系统，从而可以高效地计算有限场上散射振幅的有理系数。

Two-loop amplitudes for $\mathcal{O}(α_s^2)$ corrections to $Wγγ$ production at the LHC

We present the two-loop helicity amplitudes contributing to the next-to-next-to-leading order QCD predictions for W-boson production in association with two photons at the Large Hadron Collider. We derived compact analytic expressions for the two-loop amplitudes in the leading colour limit, and provide numerical results for the subleading colour contributions. We employ a compact system of integration-by-part identities provided by the NeatIBP package, allowing for an efficient computation of the rational coefficients of the scattering amplitudes over finite fields.
