The global fit of the Standard Model predictions to electroweak precision data, which has
been routinely performed in the past decades by several groups, led to the prediction of the …

This document summarises the current theoretical and experimental status of the di-Higgs
boson production searches, and of the direct and indirect constraints on the Higgs boson …

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 …

This article documents the muon reconstruction and identification efficiency obtained by the
ATLAS experiment for 139 fb^-1 fb-1 of pp collision data at s= 13 s= 13 TeV collected …

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 …

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 …

Algorithms used for the reconstruction and identification of electrons in the central region of
the ATLAS detector at the Large Hadron Collider (LHC) are presented in this paper; these …

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 …

The discovery of the Higgs boson in 2012, by the ATLAS and CMS experiments, was a
success achieved with only a percent of the entire dataset foreseen for the LHC. It opened a …

The observation of Higgs boson production in association with a top quark pair (tt¯ H),
based on the analysis of proton–proton collision data at a centre-of-mass energy of 13 TeV …
