We will discuss dark matter models which are related to dark
First order phase transitions (D.F.O.P.T.) in the early Universe.
D.F.O.P.T. sources an efficient materialization of dark bubbles.
Dark bubbles can scatter each others producing a gravitational
radiation background, detectable in next generation of experiments.
We will discuss the specific Framework of Majoron dark matter,
as a neutrino mass and a Warm Dark Matter genesis model. Majorons
may also be detected in next laboratory experiments: i) electron-positron
high luminosity colliders; ii) neutrino-less-double-beta decays processes; iii)
experiments searching for baryon violating Neutron-Antineutron transitions
