Exotic decays of the Higgs with photons with the CMS detector

Tanvi Wamorkar, Northeastern

The discovery of the Higgs Boson at the LHC marked the culmination of several decades of experimental research. However, the investigation of this newly discovered particle is just ramping up as a suite of experimental searches are ongoing to measure its various properties. In addition to the properties predicted in the Standard Model, the Higgs Boson may provide a portal to physics beyond the Standard Model. Its small natural width enables the Higgs Boson to easily mediate interactions with previously undiscovered physics sectors, making the search for exotic decays associated with a Higgs Boson a rich phenomenological territory to explore. In this talk, the analysis searching for the decay of the Higgs Boson to a pair of light pseudoscalars with photons in the final state will be detailed. A crucial ingredient of these results is the performance of the Compact Muon Solenoid’s (CMS) Electromagnetic Calorimeter, which will also be presented. Furthermore, the End Cap Timing layer upgrade of CMS, which is being developed for the high-luminosity era of LHC, with the goal of delivering a timing resolution of the order of tens of pico seconds will also be discussed.
