The top quark mass is one of the most intriguing parameters of the standard model (SM). Its
value indicates a Yukawa coupling close to unity, and the resulting strong ties to Higgs …

Projecting measurements of the interactions of the known Standard Model (SM) states into
an effective field theory (EFT) framework is an important goal of the LHC physics program …

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 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 algorithms used by the ATLAS Collaboration during Run 2 of the Large Hadron Collider
