Description
Mass varying neutrino (MaVaN) is a class of models which in cosmology try to explain the coincidence of dark energy density through a tracking mechanism related with neutrinos. This special model couples the quintessential scalar field with neutrino density generating an effective mass wich in turn becomes variable. Beyond its origin field, it's has been shown that MaVaN can also generate flavour conversion, in this work we analysed how the model for flavour conversion applies in cosmology and we extracted some combined bounds using cosmic microwave background, super novas, baryonic acoustic oscillations and weak lensing data.
