A search for the exclusive decays of the Higgs and Z bosons to a φ or ρ meson and a photon is performed with a pp collision data sample corresponding to an integrated
luminosity of up to 35.6 fb⁻¹ collected at √s = 13 TeV with the ATLAS detector at the
CERN Large Hadron Collider. These decays have been suggested as a probe of the Higgs
boson couplings to light quarks. No significant excess of events is observed above the
background, as expected from the Standard Model. Upper limits at 95% confidence level
were obtained on the branching fractions of the Higgs boson decays to φγ and ργ of
4.8 x 10⁻⁴ and 8.8 x 10⁻⁴, respectively. The corresponding 95% confidence level upper
limits for the Z boson decays are 0.9 x 10⁻⁶ and 25 x 10⁻⁶ for φγ and ργ, respectively.
