(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)
The results of a search for top squark (stop) pair production in final states with one isolated lepton, jets, and missing transverse momentum are reported. The analysis is performed with proton-proton collision data at s√ ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)
A search for supersymmetry (SUSY) in events with large missing transverse momentum, jets, at least one hadronically decaying tau lepton and zero or one additional light leptons (electron/muon), has been performed using ...
