Limits on the tau neutrino mass from nucleosynthesis in the presence of annihilation into majorons
Abstract
We show that in the presence of sufficiently strong tau neutrino annihilations into majorons, the primordial nucleosynthesis constraints can not rule out tau neutrino masses in the MeV range.
