Search for Higgs boson pair production in the γγ bb final state in pp collisions at √s = 13 TeV

A search is presented for the production of a pair of Higgs bosons, where one decays into two photons and the other one into a bottom quark–antiquark pair. The analysis is performed using proton–proton collision data at √s = 13 TeV recorded in 2016 by the CMS detector at the LHC, corresponding to...
