Beyond The Standard Model Higgs Searches with Photons at CMS
This event is part of the HEE Seminar Series.
The experimental discovery of the Higgs boson is one of the latest successes of the Standard Model of particle physics. Although all measurements have confirmed that this newly discovered particle is the Higgs boson predicted by the Standard Model, with no deviations to suggest otherwise, the Higgs boson can guide us to new models which modify the electoweak symmetry breaking mechanism or predict new states that couple to the Higgs. Therefore, it’s paramount to directly look for modifications of our current model with the help of the recently discovered particle. In this seminar, I will explore some of these searches, involving both Higgs exotic production (Higgs pair production) and decays (final states with photons and missing energy), particularly with final states involving photons. An important part of these analyses is the performance of the CMS Electromagnetic Calorimeter, which will also be presented.
