 Title: Search for exotic Higgs boson decays to four leptons with the ATLAS detector Author(s): Cai, Huacheng Director of Research: Martinez Outschoorn, Verena Ingrid Doctoral Committee Chair(s): Pitts, Kevin Doctoral Committee Member(s): Peng, Jen-Chieh; Shelton, Jessie; Coelho Lopes de Sa, Rafael Department / Program: Physics Discipline: Physics Degree Granting Institution: University of Illinois at Urbana-Champaign Degree: Ph.D. Genre: Dissertation Subject(s): high energy physics experiments Higgs physics beyond Standard Model physics LHC physics ATLAS detector Abstract: Searches for exotic Higgs boson decays are well motivated by various theoretical models, as well as the constraints from Higgs boson measurement results. The focus is on exotic Higgs boson decays to a pair of beyond-the-Standard-Model spin-0 particles $a$. This dissertation conducts two analyses for exotic Higgs bosons decaying into leptons, which are $H\rightarrow2a\rightarrow4\mu$ and $H\rightarrow2a\rightarrow4\tau$, and target the mass ranges of \$1 Issue Date: 2020-03-19 Type: Thesis URI: http://hdl.handle.net/2142/107860 Rights Information: Copyright 2020 Huacheng Cai Date Available in IDEALS: 2020-08-26 Date Deposited: 2020-05
