Particle mixing, flavor condensate and dark energy

arXiv:0912.1489 · doi:10.1016/j.ppnp.2009.12.073

Abstract

The mixing of neutrinos and quarks generate a vacuum condensate that, at the present epoch, behaves as a cosmological constant. The value of the dark energy is constrained today by the very small breaking of the Lorentz invariance.
