Abstract

LHC Run 1 established that there is a Higgs boson with properties so far established to be in agreement with the Standard Model Higgs Boson. There is still the firm possibility of several additional Higgs bosons of alternative masses, in various Beyond Standard Model scenarios. This project will search for BSM Higgs boson decays into dimuon pairs. This process is highly suppressed in the Standard Model, owing to the small mass of the muon with respect to other fermions, but can be enhanced in scenarios which do not respect the Yukawa structure of the couplings. Therefore this thesis will perform searches for such bosons. By the end of the PhD we will also have sensitivity to the Standard Model decay of the Higgs boson to dimuon pairs.

Country Switzerland 
Sector Public 
PI Contribution Searching for Beyond Standard Model physics. Development of software for the ATLAS High-Level Trigger. Ensuring smooth running of experiment during shifts in the ATLAS Control Room.
Collaborator Contribution More than 3000 scientists are part of the ATLAS collaboration. Each of them plays a role in ensuring efficient and safe running of the detector; coordinating the large amounts of data processing required; providing statistical and data-analysis tools as well as actually analysing the data collected.
Impact My work, when combined with similar analyses, places tight limits on the parameters of physics models, and excludes many possible Supersymmetry scenarios and Dark Matter candidates.
