NLO QCD and EW corrections to semileptonic vector-boson scattering at the LHC
by Ansgar Denner, Robert Franken, Daniele Lombardi, Santiago Lopez Portillo Chavez
A bstract: Vector-boson scattering with semileptonic final states has recently been measured at the LHC, and future experiments are expected to further increase the precision of its measurement, calling for adequate theoretical predictions. In this work, we present a calculation of the NLO QCD and electroweak corrections to the process pp → ℓ ⁺ ν _ℓ + 4j in two different fiducial regions relevant for vector-boson scattering. In a fully off-shell calculation, we provide results for the leading electroweak contribution of $$ \mathcal{O}\left({\alpha}^6\right) $$ $O (α^{6})$ and the corresponding corrections of $$ \mathcal{O}\left({\alpha}^7\right) $$ $O (α^{7})$ and $$ \mathcal{O}\left({\alpha}_s{\alpha}^6\right) $$ $O (α_{s} α^{6})$ for fiducial cross sections and a selection of differential distributions.

The cleanest of them all: NLO electroweak corrections to vector-boson scattering into doubly polarised ZZ pairs at the LHC
by Ansgar Denner, Robert Franken, Santiago Lopez Portillo Chavez, Daniele Lombardi, Giovanni Pelliccioli
A bstract: We present the first calculation of the next-to-leading-order electroweak corrections to vector-boson scattering into doubly polarised Z bosons at the LHC in the fully leptonic decay channel. The production and decay of the two polarised Z bosons are consistently modelled in the double-pole approximation, separating polarisation states at the amplitude level and including factorisable real and virtual electroweak corrections. Doubly polarised and unpolarised signals are investigated and confronted with off-shell results. A broad analysis, including results at integrated and differential level, is carried out in a realistic, CMS-inspired fiducial setup. Our study paves the way to upcoming analyses with LHC Run-3 and High-Luminosity data as well as to further phenomenological investigations.

Electroweak corrections to doubly polarised WZ scattering at the LHC
by Ansgar Denner, Robert Franken, Christoph Haitz, Daniele Lombardi, Giovanni Pelliccioli
A bstract: We present a calculation of next-to-leading-order electroweak corrections to the vector-boson scattering (VBS) process resulting in leptonically decaying W and Z bosons in association with two jets at the LHC. The VBS process is computed for both polarised and unpolarised intermediate bosons, exploiting the pole approximation and the separation of helicity states in tree-level and one-loop amplitudes. A phenomenological analysis is carried out for a realistic fiducial setup at a 13.6 TeV LHC collision energy, highlighting different patterns for the various polarisation states both at integrated and at differential level. This study provides theoretical predictions that are necessary to perform a sound characterisation of the spin structure of VBS processes with full LHC data.
