Searches for the exclusive decays of the Higgs boson to an $\\omega$ meson and a photon or a $K^{*}$ meson and a photon can probe flavour-conserving and flavour-violating Higgs boson couplings to light quarks, respectively. Searches for these decays, along with the analogous $Z$ boson decay to an $\\omega$ meson and a photon, are performed with a $pp$ collision data sample corresponding to integrated luminosities of up to 134 fb$^{-1}$ collected at $\\sqrt{s}=13$ TeV with the ATLAS detector at the CERN Large Hadron Collider. The obtained 95% confidence-level upper limits on the respective branching fractions are ${\\cal B}(H\\rightarrow\\omega\\gamma)< 5.5\\times 10^{-4}$, ${\\cal B}(H\\rightarrow K^{*}\\gamma)< 2.2\\times10^{-4}$ and ${\\cal B}(Z\\rightarrow \\omega\\gamma)<3.9\\times 10^{-6}$. The limits for $H\\rightarrow \\omega\\gamma$ and $Z\\rightarrow \\omega\\gamma$ are 370 times and 140 times the Standard Model expected values, respectively. The result for $Z\\rightarrow \\omega\\gamma$ corresponds to a two-orders-of-magnitude improvement over a the limit obtained by the DELPHI experiment at LEP.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.136515.v2/t1","@type":"Dataset","description":"Numbers of observed and expected background events for the $m_{\\mathcal{M}\\gamma}$ ranges of interest.
