We investigate the main backgrounds from SM, i.e. $Z$ boson and a photon associated production with invisible dacay of $Z$ boson, and $Z$ boson and a jet production with the jet misidentified as a photon. We find that the $p_T^{\\gamma}$ distributions of the backgrounds decrease faster than that of the signal with increasing of the transverse momentum of the photon.
