Latest results on Higgs final-states with photons in CMS

The analyses and results of standard model predicted Higgs boson with photons in the final states, using the dataset collected by the CMS experiment in proton-proton collisions during the LHC running periods in years 2011 and 2012, are reviewed. Observation of the diphoton decay mode of the recently discovered Higgs boson ($H \rightarrow \gamma\gamma$) with a local significance of 5.7 $\sigma$ and measurement of some of its properties are presented firstly. With $H \rightarrow \gamma\gamma$ channel, the Higgs boson mass is measured to be 124.70 $\pm$ 0.31 (stat.) $\pm$ 0.15 (syst.)~GeV, and the best-fit signal strength relative to the standard model prediction is 1.14 $\pm$ 0.21 (stat.) $^{+0.09}_{-0.05}$ (syst.) $^{+0.13}_{-0.09}$ (theo.). Additional measurements including the signal strength modifiers associated with different production mechanisms are also presented. Then the results of Higgs boson with di-leptons and photon, including the first limits on the Higgs boson production cross section times the $H \rightarrow Z\gamma$ branching fraction at the LHC and the first limits for the Higgs boson production cross section times the $H \rightarrow \gamma^{*}\gamma \rightarrow l^{+}l^{-}\gamma$ branching fraction for dilepton invariant mass less than 20~GeV, are summarized and presented. Finally, the upper limits at 95$\pct$ confidence-level on new particles (X) production cross-section with the new particle decaying into Higgs boson pairs in the channel $X \rightarrow HH \rightarrow \gamma\gamma b\bar{b}$, and comparisons to the predictions of some theories beyond the standard model of elementary particles based on the assumption of the existence of warped extra dimensions, are reported.
