Abstract

The Majoron provides an attractive dark matter candidate, directly associated with the mechanism responsible for spontaneous neutrino mass generation within the standard model $SU (3)_{c} \otimes SU (2)_{L} \otimes U (1)_{Y}$ framework. Here we update the cosmological and astrophysical constraints on Majoron dark matter coming from the cosmic microwave background and a variety of x- and $γ$ -ray observations.
