Description
Since the discovery of the Higgs boson in 2012, the main goal of the CMS collaboration has been to characterize the Higgs boson and measure its potential. One of the most important characteristics to measure is the Higgs boson self-coupling $\lambda$: this fundamental parameter is notably responsible for the breaking of the electroweak symmetry during the Big Bang and possibly of the predominance of matter over antimatter. Its value is predicted by the Standard Model: $\lambda$ = 0.13. Any deviation from this prediction would be synonymous with physics beyond the Standard Model.
Production of Higgs boson pairs (HH) is sensitive to probe the structure of the Higgs potential through the Higgs boson self-coupling, and to search for beyond the standard model heavy particles that couple to HH.
In this talk, we will introduce Higgs physics and the aforementioned challenges related to its study since its discovery in 2012; and we will present in a general manner the goal of the thesis, which is the search for double Higgs production decaying into 2 photons and 2 b quarks, using the Run 3 data from CMS in order to study its self-coupling $\lambda$.
