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 …

The Higgs boson was discovered by the ATLAS and CMS Collaborations in 2012 using data
from Run 1 of the Large Hadron Collider (2010− 2012). In Run 2 (2015− 2018), about 140 …

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 …

Many extensions of the Standard Model predict the production of dark matter particles at the
LHC. Sufficiently light dark matter particles may be produced in decays of the Higgs boson …

Abstract The codes HiggsBounds and HiggsSignals compare model predictions of BSM
models with extended scalar sectors to searches for additional scalars and to measurements …

The theory of the strong force, quantum chromodynamics, describes the proton in terms of
quarks and gluons. The proton is a state of two up quarks and one down quark bound by …

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 …
