This Letter presents a search for direct production of charginos and neutralinos via
electroweak interactions. The results are based on data from proton-proton collisions at a …

A bstract A study of the polarisation and CP properties in ZZ production is presented. The
used data set corresponds to an integrated luminosity of 140 fb− 1 of proton-proton …

A bstract Measurements of four-lepton differential and integrated fiducial cross-sections in
events with two same-flavour, opposite-charge electron or muon pairs are presented. The …

A bstract A search for electroweak production of supersymmetric (SUSY) particles in final
states with one lepton, a Higgs boson decaying to a pair of bottom quarks, and large missing …

We present a systematic interpretation of vector boson scattering (VBS) and diboson
measurements from the LHC in the framework of the dimension-six standard model effective …

Les Houches activities in 2021 were truncated due to the lack of an in-person component.
However, given the rapid progress in the field and the restart of the LHC, we wanted to …

A bstract Differential cross-sections are measured for the production of four charged leptons
in association with two jets. These measurements are sensitive to final states in which the …

A bstract We calculate the two-loop QCD corrections to gg→ ZZ involving a closed top-quark
loop. We present a new method to systematically construct linear combinations of Feynman …

A bstract We consider ZZ production in hadronic collisions and present state-of-the-art
predictions in QCD perturbation theory matched to parton showers. Next-to-next-to-leading …

We consider the three-loop scattering amplitudes for the production of a pair of photons in
quark-antiquark annihilation in QCD. We use suitably defined projectors to efficiently …
