 Title: A Search in the Muon Channel for Heavy Resonances Decaying to Long-Lived Neutral Particles Authors: Hunt, Adam Paul Advisors: Tully, Christopher Contributors: Physics Department Keywords: CMSDisplaced muon Subjects: Physics Issue Date: 2016 Publisher: Princeton, NJ : Princeton University Abstract: A search is performed for a heavy resonance decaying to two long-lived massive neutral particles that each decay to a pair of muons. The process is detected experimentally via a distinct topological signature consisting of a pair of oppositely charged leptons originating at a vertex significantly displaced from the LHC beam spot. Events were collected by the CMS detector at the LHC during pp collisions at $\sqrt{s} =$ 7~TeV, and selected from data samples corresponding to 5.1~fb$^{-1}$ of integrated luminosity in the muon channel. No significant excess is observed above standard model expectations, and an upper limit is set with 95\%~confidence level on the production cross section times the branching fraction to dimuons, as a function of the long-lived massive neutral particle lifetime.
