论文摘要
我们将第一次计算近近级的电动electereak和QCD校正矢量 - 玻色子散射（VBS）中的LHC上的一对Z玻璃体。我们专门考虑$ {\ rm pp \ to e^{+} e^{ - }μ^{+}μ^{ - } jj}+x $ at订单$ \ mathcal {o}（o}（α^7）$ and $ \ nathcal {o \ nathcal {o}（O}（α_Sα）$ and cromption and crounter and crounter and contrive and contription unter。由于存在增强的Sudakov对数，因此电动校正的校正为$ -16 \％$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $。另一方面，QCD校正比VBS中的典型QCD校正大（$+24 \％$）。这起源于考虑完整的计算，包括在相当包容的相位空间中的三 - 玻色子贡献。我们还为$ {\ rm pp \ to e^{+} e^{ - }μ^{+}μ^{ - } jj}+x $在现实设置中提供了对横截面的所有贡献的前阶分析。
We present the first calculation of the full next-to-leading-order electroweak and QCD corrections for vector-boson scattering (VBS) into a pair of Z bosons at the LHC. We consider specifically the process ${\rm pp\to e^{+}e^{-}μ^{+}μ^{-}jj}+X$ at orders $\mathcal{O}(α^7)$ and $\mathcal{O}(α_sα^6)$ and take all off-shell and interference contributions into account. Owing to the presence of enhanced Sudakov logarithms, the electroweak corrections amount to $-16\%$ of the leading-order electroweak fiducial cross section and induce significant shape distortions of differential distributions. The QCD corrections on the other hand are larger ($+24\%$) than typical QCD corrections in VBS. This originates from considering the full computation including tri-boson contributions in a rather inclusive phase space. We also provide a leading-order analysis of all contributions to the cross section for ${\rm pp \to e^{+}e^{-}μ^{+}μ^{-}jj}+X$ in a realistic setup.
