A search for the narrow structure, Xð5568Þ, reported by the D0 Collaboration in the decay sequence X → B0 sπ , B0 s → J=ψϕ, is presented. The analysis is based on a data sample recorded with the ATLAS detector at the LHC ...
Search for high-mass resonances decaying to τν in pp collisions at √s=13 TeV with the ATLAS detector
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
A search for high-mass resonances decaying to τν using proton-proton collisions at ffiffi s p ¼ 13 TeV produced by the Large Hadron Collider is presented. Only τ-lepton decays with hadrons in the final state are considered. ...
