Visible decays: search for axion-like particles (ALPs) via h → Z a (a → gamma gamma). Preliminary study from Bauer, Neubert, Thamm, arXiv:1708.00443. They put limits on very light ALPs (m_a < 47 MeV) from constraints on h → Z gamma, since for m_a < 47 MeV the two photons from the ALP decay are very collimated and seen as one in the detector. For not-so-light ALPs, they compute just number of signal events.
Goal would be to provide a better estimate of LHC sensitivity to h → Z a, a → gamma gamma resolved (including some sort of background study?).
