Search for exotic Higgs boson decays H $\to$ $\mathcal{AA}$ with $\mathcal{AA}$ $\to$ $\gamma \gamma$ in events with a semi-merged topology in proton-proton collisions at $\sqrt{s}$ = 13 TeV

CMS Collaboration

A search for exotic Higgs boson decays H $\to$ $\mathcal{AA}$, with $\mathcal{A}$ $\to$ $\gamma \gamma$ is presented, using events with a semi-merged topology. One of the hypothetical particl…
