We lay out a comprehensive physics case for a future high-energy muon collider, exploring
a range of collision energies (from 1 to 100 TeV) and luminosities. We highlight the …

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 …

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 …

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 …

Combined measurements of Higgs boson production cross sections and branching fractions
are presented. The combination is based on the analyses of the Higgs boson decay modes …

A precise knowledge of the quark and gluon structure of the proton, encoded by the parton
distribution functions (PDFs), is of paramount importance for the interpretation of high …
