| Abstract: | A search is presented for an extended Higgs sector with two new particles, π and π, in the process πβπβ’πβ(πΎβ’πΎ)β’(πΎβ’πΎ). Novel neural networks classify events with diphotons that are merged and determine the diphoton masses. The search uses LHC proton-proton collision data at βπ =13ββTeV collected with the CMS detector, corresponding to an integrated luminosity of 138ββfbβ1. No evidence of such resonances is seen. Upper limits are set on the production cross section for ππ between 300 and 3000 GeV and ππ/ππ between 0.5% and 2.5%, representing the most sensitive search in this channel. |
