Özet
We present a dark matter model for explaining the observed 130 GeV photon line from the galaxy center. The dark matter candidate is a vector boson of mass my with a dimensionless coupling to the photon and Z boson. The model predicts a double line photon spectrum at energies equal to m(v) and m(v) (1 - m(z)(2)/m(v)(2)) originating from the dark matter annihilation. The same coupling leads to a mono-photon plus zi v missing energy signal at the LHC. The entire perturbative parameter space can be probed by the 14 TeV LHC run. The model has also a good prospect of being probed by direct dark matter searches as well as the measurement of the rates of h -> gamma gamma and h -> Z gamma at the LHC. (C) 2013 Elsevier B.V.
