Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU (3) gauge symmetry with charges called “color quantum numbers” …

We review the physics opportunities of the Future Circular Collider, covering its e+ e-, pp, ep
and heavy ion programmes. We describe the measurement capabilities of each FCC …

In July 2012, the ATLAS and CMS collaborations at the CERN Large Hadron Collider
announced the observation of a Higgs boson at a mass of around 125 gigaelectronvolts …

The standard model of particle physics,,–describes the known fundamental particles and
forces that make up our Universe, with the exception of gravity. One of the central features of …

Constraints on the Higgs boson self-coupling are set by combining double-Higgs boson
analyses in the bb¯ bb¯, bb¯ τ+ τ− and bb¯ γ γ decay channels with single-Higgs boson …

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 …

Searches are performed for nonresonant and resonant di-Higgs boson production in the bb¯
γ γ final state. The dataset used corresponds to an integrated luminosity of 139 fb-1 of proton …

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 …

Results of a search for new physics in final states with an energetic jet and large missing
transverse momentum are reported. The search uses proton-proton collision data …
