¹	AABOUD 2018AU search for the $Z$ $\to$ $ϕ γ$ decay mode where the $ϕ$ is identified through its decay $ϕ$ $\to$ $K^{+} K^{-}$ . In the data corresponding to 32.3 fb $^{- 1}$ , 3,364 events are selected for 1012 $<$ m( $K^{+} K^{-}$ ) $<$ 1028 MeV. See erratum AABOUD 2023A.

²	AABOUD 2016K search for the $Z$ $\to$ $ϕ γ$ decay mode where the $ϕ$ is identified through its decay into $K^{+} K^{-}$ . In the data corresponding to a total luminosity of 2.7 $fb^{- 1}$ , 1065 events are selected and their $K^{+} K^{-} γ$ invariant mass spectrum is analyzed.
