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 ...

The result of a search for the pair production of the lightest supersymmetric partner of the bottom quark (˜b1) using 139 fb−1 of proton-proton data collected at √ s = 13 TeV by the ATLAS detector is reported. In the ...

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 ...

Measurements of K0S and Λ0 production in tt¯ final states have been performed. They are based on a data sample with integrated luminosity of 4.6 fb−1 from proton–proton collisions at a centre-of-mass energy of 7 TeV, ...

The momentum measurement capability of the ATLAS muon spectrometer relies fundamentally on the intrinsic single-hit spatial resolution of the monitored drift tube precision tracking chambers. Optimal resolution is achieved ...

The differential cross section for isolated-photon production in pp collisions is measured at a centre-of-mass energy of 13 TeV with the ATLAS detector at the LHC using an integrated luminosity of 36.1 fb−1 . The differential ...

This paper describes a study of techniques for identifying Higgs bosons at high transverse momenta decaying into bottom-quark pairs, H → bb¯, for proton–proton collision data collected by the ATLAS detector at the Large ...
