10 Neutrinos

In this chapter we shall discuss neutrino physics. As anticipated in Sections 3.8 and 4.11, neutrinos produced with a certain flavour, νe, νμ or ντ, may be detected later with a different flavour, if enough time is left between production and detection. Consequently νe, νμ and ντ are not stationary states with definite mass, but quantum superpositions of them. We call ν1, ν2 and ν3 the states of definite mass. Neutrinos can change flavour by two mechanisms: oscillations and matter effects.

We start by presenting the formal description of neutrino mixing, showing, in particular, the analogies and the differences with the quarks. We will give the current values of the mixing angles and masses that have been measured.
