Description
While photon lines - or monochromatic photons-are known to arise in many dark matter models, neutrino lines are not so common. In this talk, I will discuss simple dark matter models, whose main indirect detection signature is the production of monochromatic neutrinos. Such features play an important role in indirect dark matter searches because they can be better discriminated against the astrophysical background. In the first part of my talk, I will discuss decaying dark matter. In particular, I will focus on singlet majorons, which naturally produce neutrino lines. Then, in the second part,I will briefly describe the properties that simple models must have in order to produce, in the near future,an observable flux of neutrino lines from dark matter annihilations. In both parts, I will discuss the implications for neutrino telescopes and the interplay with other indirect detection channels.
