Annihilation of light dark matter into photons in model-independent approach

Abstract

We examine annihilation of light bosonic Dark Matter into pair of photons in model-independent way. We consider the simplest generic Lagrangian describing such process and then compare results to the available experimental data. Then we match our results with particular Dark matter models and determine possible constrains onto parameter space of those models.
