neutrino oscillati<strong>on</strong>s<br />
solar, atmospheric, reactor, beam<br />
neutrinos give a nice picture of the<br />
oscillati<strong>on</strong> of three active flavors<br />
δm 2 12 ∼ 7.6 × 10 −5 eV 2<br />
sin 2 θ 12 ∼ 0.3<br />
δm 2 23 ∼ 2.4 × 10 −3 eV 2<br />
sin 2 θ 23 ∼ 0.4<br />
sin 2 θ 13 ∼ small<br />
neutrino oscillati<strong>on</strong>s are now a firmly<br />
established experimental fact<br />
the MSW-LMA soluti<strong>on</strong> for solar<br />
neutrinos predicts an energy-dependent<br />
survival probability for electr<strong>on</strong> neutrinos<br />
