Distinguishing between Dirac and Majorana neutrinos with two-particle interferometry

Phys Rev Lett. 2006 Mar 31;96(12):121802. doi: 10.1103/PhysRevLett.96.121802. Epub 2006 Mar 31.


Two-particle interferometry, a second-order interference effect, is explored as another possible tool to distinguish between massive Dirac and Majorana neutrinos. A simple theoretical framework is discussed in the context of several gedanken experiments. The method can in principle provide both the mass scale and the quantum nature of the neutrino for a certain class of incoherent left-handed source currents.
