 A Search for Emerging Jets at sqrt{s} = 13 TeV at ATLAS Run 2 / Treado, Colleen Jennifer A search is presented for emerging jets, new exotic objects arising in models with QCD- like hidden sectors where dark quarks undergo dark showering, yielding long-lived dark hadrons that subsequently decay to visible jets with multiple small and varyingly-displaced vertices within the jet cone [...] CERN-THESIS-2020-242 - 434 p.
