Light-by-light scattering (γγ→ γγ) is a quantum-mechanical process that is forbidden in the
classical theory of electrodynamics. This reaction is accessible at the Large Hadron Collider …

High-precision measurements by the ATLAS Collaboration are presented of inclusive W^+

A measurement of the production processes of the recently discovered Higgs boson is
performed in the two-photon final state using 4.5 fb-1 of proton-proton collisions data at s= 7 …

We report the observation of Higgs boson decays to WW* based on an excess over
background of 6.1 standard deviations in the dilepton final state, where the Standard Model …

This paper reports a detailed study of techniques for identifying boosted, hadronically
decaying W bosons using 20.3 fb^-1-1 of proton–proton collision data collected by the …

During 2015 the ATLAS experiment recorded\(3.8\,{\mathrm {fb}}^{-1}\) of proton–proton
collision data at a centre-of-mass energy of\(13\,{\mathrm {TeV}}\). The ATLAS trigger system …
