Search for Higgs and $Z$ Boson Decays to $\phi\,\gamma$ with the ATLAS Detector

Pages: 27

Abstract: A search for the decays of the Higgs and $Z$ bosons to a $\phi$ meson and a photon is performed with a $pp$ collision data sample corresponding to an integrated luminosity of 2.7 fb$^{-1}$ collected at $\sqrt{s}=$13 TeV with the ATLAS detector at the LHC. No significant excess of events is observed above the background, and 95% confidence level upper limits on the branching fractions of the Higgs and $Z$ boson decays to $\phi\,\gamma$ of 1.4$\times$10$^{-3}$ and 8.3$\times$10$^{-6}$, respectively, are obtained.
