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 …

This document provides a comprehensive summary of the state-of-the-art, challenges, and
prospects in the experimental and theoretical study of the strong coupling $\alpha_s $. The …

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 …

The performance of the ATLAS muon trigger system is evaluated with proton-proton ($ pp $)
and heavy-ion (HI) collision data collected in Run 2 during 2015-2018 at the Large Hadron …

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 …

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 …

We present the new version of OpenLoops, an automated generator of tree and one-loop
scattering amplitudes based on the open-loop recursion. One main novelty of OpenLoops 2 …

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 …

A measurement of the mass of the Higgs boson in the diphoton decay channel is presented.
This analysis is based on 35.9 fb− 1 of proton-proton collision data collected during the 2016 …
