Title: Natural explanation for the 130GeV photon line within a vector boson dark matter model

Presenter: Yasaman Farzan (IMP Teheran)

Chair: Nuria Rius (Valencia U)

Abstract: After a brief review of the 130 GeV photon line from the galaxy center, I will present a dark matter model explaining this line. In this model, the dark matter candidate is a vector boson of mass $m_V$ 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 $m_V(1-m_Z^2/4m_V^2)$ originating from the dark matter annihilation.
The same coupling leads to a mono-photon plus 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 $h \to \gamma \gamma$ and $h \to Z \gamma$ at the LHC.
