dc.description.abstract	A search is presented for an extended Higgs sector with two new particles, X and Ø , in the process X-ØØ-(yy)(yy). Novel neural networks classify events with diphotons that are merged and determine the diphoton masses. The search uses LHC proton-proton collision data at V¯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 mx between 300 and 3000 GeV and mØ/mx between 0.5% and 2.5%, representing the most sensitive search in this channel.	es_ES
dc.description.sponsorship	We congratulate our colleagues in the CERN accelerator departments forthe excellent performance of the LHC and thank the technical and administrative staffs at CERN and at other CMS institutes for their contributions to the success of the CMS effort. In addition, we gratefully acknowledge the computing centers and personnel of the Worldwide LHC Computing Grid and other centers for delivering so effectively the computing infrastructure essential to our analyses.
