Neutrino Oscillations

Abstract

At present, most experimental limits on the neutrino masses are consistent with zero.¹ Nevertheless several theoretical and cosmological arguments indicate that these masses should be finite. The purpose of the following chapter is to give an example of how one can measure the neutrino mass differences using a quantum oscillation effect. The underlying theory is based on the idea that the two neutrinos ν _e and ν _μ are actually two different states of the same physical entity which we will call a “neutrino”.
