The paper
Abstract
We study decoherence effects on mixing among three generations of neutrinos. We show that in presence of a non–diagonal dissipation matrix, both Dirac and Majorana neutrinos can violate the CPT symmetry and the oscillation formulae depend on the parametrization of the mixing matrix. We reveal the CP violation in the transitions preserving the flavor, for a certain form of the dissipator. In particular, the CP violation affects all the transitions in the case of Majorana neutrinos, unlike Dirac neutrinos which still preserve the CP symmetry in one of the transitions flavor preserving. This theoretical result shows that decoherence effects, if exist for neutrinos, could allow to determine the neutrino nature and to test fundamental symmetries of physics. Next long baseline experiments could allow such an analysis. We relate our study with experiments by using the characteristic parameters and the constraints on the elements of the dissipation matrix of current experiments.

Neutrino decoherence is often represented using an open quantum system formalism [ref] considering both the neutrino and its environment, and beyond neutrinos this formalism has also be employed to study decoherence resulting from gravitational sources more generally [ref] .
