NLO QCD and EW corrections to vector-boson scattering into ZZ at the LHC

Understand

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 ${\rm pp\to e^{+}e^{-}\mu^{+}\mu^{-}jj}+X$ at orders $\mathcal{O}(\alpha^7)$ and $\mathcal{O}(\alpha_s\alpha^6)$ 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.
