Neutrino capture on tritium as a probe of flavor vacuum condensate and dark matter

We show that the study of neutrino capture on tritium, for non-relativistic neutrinos, can allow to distinguish among various models, eventually prove quantum field theory condensation effects and permit test hypothesis according which flavor vacuum energy gives a contribution dark matter universe. Indeed, we rate depends model considered, it brings an imprint condensate. Experiments like PTOLEMY, designed reveal cosmic background, then give indication existence component induced by mixing.
