(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
A search for magnetic monopoles and high-electric-charge objects is presented using 34.4 fb−1 of 13 TeV pp collision data collected by the ATLAS detector at the LHC during 2015 and 2016. The considered signature is based ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
A search for heavy resonances decaying into a W or Z boson and a Higgs boson produced in proton−proton collisions at the Large Hadron Collider at √s=13 TeV is presented. The analysis utilizes the dominant W→q¯q′ or Z→q¯q ...
