Higgs precision measurements at the LHC and at the future circular colllider

The research project aims, first, to develop data analysis techniques for measuring the trilinear coupling of the Higgs boson with itself, which would provide an important test of the Higgs mechanism by determining the shape of the Higgs potential. Experimentally, this coupling can be extracted by measuring the non-resonant production cross section of Higgs boson (HH) pairs at the LHC and the future circular collider, currently under preparation at CERN. Specifically, the project intends to study the production of double Higgs in final states with a pair of b-jets and charged leptons using advanced machine learning techniques, by using data collected by the CMS experiment.
