The majoron provides an attractive dark matter candidate, directly associated to the mechanism responsible for spontaneous neutrino mass generation within the standard model framework. Here we update the cosmological and astrophysical constraints on majoron dark matter which come from the Cosmic Microwave Background (CMB) and a variety of X- and gamma-ray observations.

Minimal Majoron Dark Matter
In the minimal Majoron model the particle can explain all dark matter with mass below about 10 MeV from misalignment or freeze-in, and remains compatible with thermal leptogenesis when misalignment dominates or with m...
