A search is presented for an extended Higgs sector with two new particles, 𝑋
and 𝜙
, in the process 𝑋β𝜙β’𝜙β(𝛾β’𝛾)β’(𝛾β’𝛾)
. Novel neural networks classify events with diphotons that are merged and determine the diphoton masses. The search uses LHC proton-proton collision data at β𝑠=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 𝑚𝑋
between 300 and 3000 GeV and 𝑚𝜙/𝑚𝑋
between 0.5% and 2.5%, representing the most sensitive search in this channel. |
