Search for new resonances decaying to pairs of merged diphotons in proton-proton collisions at $\sqrt{s}$ = 13 TeV

CMS Collaboration

A search is presented for an extended Higgs sector with two new particles, X and $\varphi$, in the process X $\to$ $\varphi \varphi$ $\to$ $(\gamma \gamma )(\gamma \gamma )$. Novel neural networks classify events with dipho…
