Correspondingly, large rates for the $H\\to \\gamma\\bar \\gamma$ decay become plausible, giving rise to one monochromatic photon with $E^{\\gamma}\\simeq m_H/2$ (i.e., more than twice the photon energy in the rare standard-model decay $H\\to \\gamma Z\\to\\gamma\\bar\\nu\\nu$), and a similar amount of missing energy.
