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 Measurements of Higgs boson production cross-sections are carried out in the
diphoton decay channel using 139 fb− 1 of pp collision data at\(\sqrt {s}\)= 13 TeV collected …

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 …

We provide an overview of the status of Monte-Carlo event generators for high-energy
particle physics. Guided by the experimental needs and requirements, we highlight areas of …

A bstract We investigate the high-p T tails of the pp→ ℓν and pp→ ℓℓ Drell-Yan processes as
probes of New Physics in semileptonic interactions with an arbitrary flavor structure. For this …

A bstract Cross-section measurements of top-quark pair production where the hadronically
decaying top quark has transverse momentum greater than 355 GeV and the other top quark …

A bstract The SMEFTsim package [1] is designed to enable automated computations in the
Standard Model Effective Field Theory (SMEFT), where the SM Lagrangian is extended with …

A bstract We assess the impact of top quark production at the LHC on global analyses of
parton distributions (PDFs) and of Wilson coefficients in the SMEFT, both separately and in …
