Pa. Raczka et al., EXPERIMENTAL CONSTRAINTS ON THE NEUTRINO OSCILLATIONS AND A SIMPLE-MODEL OF 3-FLAVOR MIXING, Physical review. D. Particles and fields, 49(3), 1994, pp. 1655-1658
A simple model of neutrino mixing is considered which contains only on
e right-handed neutrino field coupled, via the mass term, to the three
usual left-handed fields. This is the simplest model that allows for
three-flavor neutrino oscillations. The existing experimental limits o
n the neutrino oscillations are used to obtain constraints on the two
free-mixing parameters of the model. A specific sum rule relating the
oscillation probabilities of different flavors is derived.
