The expected Higgs and Z boson signal yields, along with the total systematic uncertainty,for ϕγ and ργ, estimated using simulations, are also shown in parentheses.Branching Fraction Limit (95% CL) Expected ObservedB (H → ϕγ) [ 10−4 ] 4.2+1.8−1.2 5.0B (Z → ϕγ) [ 10−6 ] 1.1+0.5−0.3 0.7B (H → ργ) [ 10−4 ] 10.0+4.9−2.8 10.4B (Z → ργ) [ 10−6 ] 5.1+2.1−1.4 4.0Table 3. Expected and observed branching fraction upper limits at 95% CL for the ϕγ and ργanalyses. The ±1σ intervals of the expected limits are also given.One correction is noted for the paper. The calculation of an angle used to account for mesonpolarisation in the signal decays was not correct. Amending this leads to a modificationof the pT distributions of the decay products in the signal decays, which propagates tothe signal yields and efficiencies, and the extracted 95% confidence-level (CL) upper limitson the branching fractions for each signal. The trigger efficiency for both the Higgs andZ boson decays to ϕγ is approximately 83% with respect to the offline selection. Thetrigger efficiency for Higgs boson decays to ργ is 78%, while for the correspondin…
