Abstract The Forward Physics Facility (FPF) is a proposal to create a cavern with the space
and infrastructure to support a suite of far-forward experiments at the Large Hadron Collider …

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” …

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 …

High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large
number of particles along the beam collision axis, outside of the acceptance of existing LHC …

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 …

The ATLAS experiment has developed extensive software and distributed computing
systems for Run 3 of the LHC. These systems are described in detail, including software …

A bstract A direct search for Higgs bosons produced via vector-boson fusion and
subsequently decaying into invisible particles is reported. The analysis uses 139 fb− 1 of pp …

A search for resonant Higgs boson pair production in the bb¯ bb¯ final state is presented.
The analysis uses 126 fb-1–139 fb-1 of pp collision data at s= 13 TeV collected with the …

Multijet rates at hadron colliders provide a unique possibility for probing quantum
chromodynamics (QCD), the theory of strong interactions. By comparing theory predictions …

The successful operation of the Large Hadron Collider (LHC) and the excellent performance
of the ATLAS, CMS, LHCb and ALICE detectors in Run-1 and Run-2 with $ pp $ collisions at …
