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 …

Abstract The Large Hadron Collider at CERN, delivering proton–proton collisions at much
higher energies and far higher luminosities than previous machines, has enabled a …

A bstract A rather general method for determining the spin density matrix of a multi-particle
system from angular decay data is presented. The method is based on a Bloch …

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 …

Measurements of joint-polarisation states of W and Z gauge bosons in W±Z production are
presented. The data set used corresponds to an integrated luminosity of 139 fb− 1 of proton …

A bstract Recent developments in the Standard Model analysis of semileptonic charged-
current processes involving light quarks have revealed~ 3σ tensions in Cabibbo universality …

A bstract This study explores fully leptonic WZ and WW production at the LHC within the
SMEFT framework at NLO in QCD, focusing on both CP-even and CP-odd triple-gauge …

The identification of prompt and isolated muons, as well as muons from heavy-flavour
hadron decays, is an important task. We developed two multivariate techniques to provide …

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 …
