This paper presents the observation of four-top-quark (tt¯ tt¯) production in proton-proton
collisions at the LHC. The analysis is performed using an integrated luminosity of 140 fb-1 at …

A bstract We present a global interpretation of Higgs, diboson, and top quark production and
decay measurements from the LHC in the framework of the Standard Model Effective Field …

A bstract The search for effective field theory deformations of the Standard Model (SM) is a
major goal of particle physics that can benefit from a global approach in the framework of the …

A bstract We study the phenomenology of a strongly-interacting top quark at future hadron
and lepton colliders, showing that the characteristic four-top contact operators give rise to …

A bstract The production of a top quark-antiquark pair in association with a W boson
(\(\textrm {t}\overline {\textrm {t}}\textrm {W}\)) is measured in proton-proton collisions at a …

The production of a top-antitop quark pair in association with a W boson (tt¯ W) is one of the
heaviest signatures currently probed at the Large Hadron Collider. Since the first …

A bstract The results of a search for direct pair production of top squarks and for dark matter
in events with two opposite-charge leptons (electrons or muons), jets and missing transverse …

Measurements of both the inclusive and differential production cross sections of a top-quark–
antiquark pair in association with a Z boson (\(t {\bar {t}} Z\)) are presented. The …

The standard model (SM) production of four top quarks (tttt) in proton–proton collisions is
studied by the CMS Collaboration. The data sample, collected during the 2016–2018 data …

A bstract We introduce an improvement to the FxFx matrix element merging procedure for
pp→\(t\overline {t} W\) production at NLO in QCD with one and/or two additional jets. The …
