This paper presents a measurement of quantities related to the formation of jets from high-energy quarks and gluons (fragmentation). Jets with transverse momentum 100 GeV <pT<2.5 TeV and pseudorapidity |η|<2.1 from an ...

This paper describes the reconstruction of electrons and photons with the ATLAS detector, employed for measurements and searches exploiting the complete LHC Run 2 dataset. An improved energy clustering algorithm is introduced, ...
Observation of light-by-light scattering in ultraperipheral Pb+Pb collisions with the ATLAS detector
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)

This paper presents measurements of the W+ → μ+ν and W− → μ−ν cross-sections and the associated charge asymmetry as a function of the absolute pseudorapidity of the decay muon. The data were collected in proton– proton ...

The problems of neutrino masses, matter-antimatter asymmetry, and dark matter could be successfully addressed by postulating right-handed neutrinos with Majorana masses below the electroweak scale. In this work, leptonic ...
