(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 ...
