Searches for exclusive decays of the Higgs boson into $D^*\\gamma$ and of the $Z$ boson into $D^0\\gamma$ and $K^0_s\\gamma$ can probe flavour-violating Higgs boson and $Z$ boson couplings to light quarks. Searches for these decays are performed with a $pp$ collision data sample corresponding to an integrated luminosity of $136.3$ fb$^{-1}$ collected at $\\sqrt{s}=13$ TeV between 2016--2018 with the ATLAS detector at the CERN Large Hadron Collider. In the $D^*\\gamma$ and $D^0\\gamma$ channels, the observed (expected) 95% confidence-level upper limits on the respective branching fractions are ${\\cal B}(H\\rightarrow D^*\\gamma)< 1.0 (1.2)\\times 10^{-3}$, ${\\cal B}(Z\\rightarrow D^0\\gamma)< 4.0 (3.4)\\times 10^{-6}$, while the corresponding results in the $K^0_s\\gamma$ channel are ${\\cal B}(Z\\rightarrow K^0_s\\gamma)< 3.1 (3.0)\\times 10^{-6}$.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.147194.v1/t1","@type":"Dataset","description":"Numbers of observed and expected background events for the $m_{\\mathcal{M}\\gamma}$ ranges of interest.
