Particle physics today faces the challenge of explaining the mystery of dark matter, the origin
of matter over anti-matter in the Universe, the origin of the neutrino masses, the apparent …

Specialized data-taking and data-processing techniques were introduced by the CMS
experiment in Run 1 of the CERN LHC to enhance the sensitivity of searches for new …

The luminosity determination for the ATLAS detector at the LHC during Run 2 is presented,
with $ pp $ collisions at $\sqrt {s}= 13$ TeV. The absolute luminosity scale is determined …

The flavour-tagging algorithms developed by the ATLAS Collaboration and used to analyse
its dataset of\(\sqrt {s}= 13\) TeV pp collisions from Run 2 of the Large Hadron Collider are …

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 …

Detector and event visualization are essential parts of the software used in high-energy
physics (HEP) experiments. Modern visualization techniques and multimedia production …

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 …

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 …

The observation of the production of four top quarks in proton-proton collisions is reported,
based on a data sample collected by the CMS experiment at a center-of-mass energy of 13 …
