(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
A search for new phenomena with top quark pairs in final states with one isolated electron or muon, multiple jets, and large missing transverse momentum is performed. Signal regions are designed to search for two-, three-, ...
