The field of particle physics is at the crossroads. The discovery of a Higgs-like boson
completed the Standard Model (SM), but the lacking observation of convincing resonances …

The observation of the production of four top quarks in proton-proton collisions is reported,
based on a data sample collected by the CMS experiment at a center-of-mass energy of 13 …

A bstract The first measurement of the top quark pair (\(\textrm {t}\overline {\textrm {t}}\))
production cross section in proton-proton collisions at\(\sqrt {s}\)= 13. 6 TeV is presented …

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 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 …

We perform a complete study of the electroweak precision observables and electroweak
gauge boson pair production in terms of the Standard Model effective field theory up to O …

A bstract Fiducial and differential cross-section measurements of W+ W− production in
association with at least one hadronic jet are presented. These measurements are sensitive …
