Study of associate production of the Higgs boson in the diphoton decay channel at the CMS experiment

摘要

The observation of a boson compatible with the Standard Model (SM) Higgs particle is the starting point for the complete understanding of the electroweak symmetry-breaking mechanism. More specifically, the exact determination of the Higgs couplings to bosons and fermions is crucial to establish if the properties of this particle are compatible with the theoretical predictions. In order to achieve a good sensitivity in couplings measurements it is important to consider those production modes where the Higgs boson is produced in association with W/Z bosons or quarks. The characteristic topology of these events allows to perform an exclusive analysis, crucial for accurate measurements of couplings.
