(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
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 ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
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 ...

Studies of the fragmentation of jets into charged particles in heavy-ion collisions can provide information about the mechanism of jet quenching by the hot and dense QCD matter created in such collisions, the quark-gluon ...

To assess the properties of the quark–gluon plasma formed in ultrarelativistic ion collisions, the ATLAS experiment at the LHC measures a correlation between the mean transverse momentum and the flow harmonics. The analysis ...

The algorithms used by the ATLAS Collaboration during Run 2 of the Large Hadron Collider to identify jets containing b-hadrons are presented. The performance of the algorithms is evaluated in the simulation and the efficiency ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
A search for supersymmetric partners of gluons and quarks is presented, involving signatures with jets and either two isolated leptons (electrons or muons) with the same electric charge, or at least three isolated leptons. ...
