我们计算了电子-核子碰撞中包含射产生的O(α2αS 2)微扰修正。这一过程对未来的电子离子对撞机(EIC)的物理计划特别感兴趣。我们包括了所有相关的部分子过程，包括深度非弹性散射贡献，光子引发的修正，以及首次出现在这个级数的部分子-部分子散射项。在对末态强子相空间进行积分后，我们验证了我们的结果与已知的次次优序结构函数(NNLO)的深度非弹性修正。我们的计算使用N-Jettness减法进行高阶计算，并允许对深度非弹性散射过程进行完全不同的描述。我们详细描述了这种方法在包含式喷注生产中的应用，并给出了所提出的EIC的唯象结果。NNLO修正对喷流运动学有很大的依赖性，并且产生于所有贡献的部分子通道之间错综复杂的相互作用。
We compute the O (α 2 α s 2) perturbative corrections to inclusive jet production in electron–nucleon collisions. This process is of particular interest to the physics program of a future Electron Ion Collider (EIC). We include all relevant partonic processes, including deep-inelastic scattering contributions, photon-initiated corrections, and parton–parton scattering terms that first appear at this order. Upon integration over the final-state hadronic phase space we validate our results for the deep-inelastic corrections against the known next-to-next-to-leading order (NNLO) structure functions. Our calculation uses the N-jettiness subtraction scheme for performing higher-order computations, and allows for a completely differential description of the deep-inelastic scattering process. We describe the application of this method to inclusive jet production in detail, and present phenomenological results for the proposed EIC. The NNLO corrections have a non-trivial dependence on the jet kinematics and arise from an intricate interplay between all contributing partonic channels.
