Abstract: | We present the first direct search for exotic Higgs boson decays H → AA, A → γγ in events with two photonlike objects. The hypothetical particle A is a low-mass spin-0 particle decaying promptly to a merged diphoton reconstructed as a single photonlike object. We analyze the data collected by the CMS experiment at s√ = 13 TeV corresponding to an integrated luminosity of 136 fb−1. No excess above the estimated background is found. We set upper limits on the branching fraction B(H → AA → 4γ) of (0.9-3.3) × 10−3 at 95% confidence level for masses of A in the range 0.1-1.2 GeV. |
