A generic feature of many neutrino mass models is the prediction of a pseudo-Goldstone mode arising from the spontaneous symmetry breaking of lepton number. This new particle, the so-called majoron, can modify the evolution of the energy density of the Universe and damp neutrino perturbations around the time of recombination, leading to distinctive signatures in the CMB. I will show that...

There is a remarkable similarity between the dark matter mass density, of unknown origins, and the baryonic mass density which originates from a minuscule 1 in 10 billion asymmetry between matter and antimatter.
Asymmetric dark matter models propose that a connected asymmetry generation mechanism is responsible for the abundance of both sectors.
In this talk I will review these motivations...
