We present the first analytical results for the O(αα_{s}) corrections to the total cross section for the inclusive production of an on-shell Z boson at hadron colliders. We include the complete set of contributions, with photonic and massive weak gauge boson effects, which have been computed in analytical form and expressed in terms of polylogarithmic and elliptic integrals. We present numerical results, relevant for the precision studies at the LHC. These corrections increase the accuracy of the predictions and contribute to the reduction of the QCD component of the theoretical uncertainty.
我们给出了强子对撞机上产生一个壳上Z玻色子的总截面的O(ααₛ)修正的首个解析结果。我们纳入了完整的贡献集，包括光子和有质量的弱规范玻色子效应，这些效应已以解析形式计算出来，并以多重对数积分和椭圆积分表示。我们给出了与大型强子对撞机精度研究相关的数值结果。这些修正提高了预测的准确性，并有助于降低理论不确定性中的量子色动力学部分。
