Abstract

The prospects for the study of the production of a pair of Higgs bosons (HH), where one decays into two photons and the other one into a bottom quark-antiquark pair, are presented for a center-of-mass energy of 14 TeV at the High-Luminosity LHC. The analysis is developed using a parametric simulation of the Phase-II upgraded CMS detector and optimized for an integrated luminosity of 3000 fb−1. The projected statistical sensitivity of this decay channel for the standard model HH signal is about 1.8σ, the highest among the decay channels considered for HH searches. Projections are also presented for the measurement of the Higgs boson self-coupling λ3.
