The search focuses on final states where both long lived particles decay within the hadronic calorimeter of the detector, resulting in jets with unusual properties. No excess was observed and limits were set on the lifetime of the long lived particles for various combinations of scalar boson and long lived particle masses. dc.format.mimetype application/pdf dc.language.iso en_US dc.rights none dc.subject ATLAS dc.subject LHC dc.subject Long-lived particles dc.subject Physics dc.subject.other Physics dc.title A Search for Long Lived Neutral Particles Decaying to Hadronic States in Proton-Proton Collisions in the ATLAS Detector at sqrt(s) = 8 TeV and sqrt(s) = 13 TeV at the LHC dc.type Thesis dc.embargo.terms Open Access
