Search for New Resonances Decaying to Pairs of Merged Diphotons in Proton-Proton Collisions at √s=13 TeV
Original language description
A search is presented for an extended Higgs sector with two new particles, X and., in the process X ->phi phi ->(gamma gamma)(gamma gamma).Novel neural networks classify events with diphotons that are merged and determine the diphoton masses. The search uses LHC proton-proton collision data at root s = 13 TeV collected with the CMS detector, corresponding to an integrated luminosity of 138 fb(-1). No evidence of such resonances is seen. Upper limits are set on the production cross section for m(X) between 300 and 3000 GeV and m.=m(X) between 0.5% and 2.5%, representing the most sensitive search in this channel.
