Monophoton search

We present a search for ADD, Branon large extra dimensions and dark matter pair-production with a final state of $\gamma$ + missing transverse energy in pp collisions at $\sqrt{s}=8\,\mathrm{TeV}$. We find no deviation from the Standard Model prediction for this final state, and achieve an extension of the current limits on parameter space. This study is done with the data taken by the CMS experiment at the LHC in 2012 corresponding to an integrated luminosity of $19.6\,\mathrm{fb^{-1}}$ of data.
