The phenomenon presents us with purely quantum mechanical effects over macroscopic time and distance scales (milliseconds and 1000s of km).

Neutrino oscillations have in the following years become the principal interest of Pontecorvo and his collaborators. If the neutrino has enough energy, it will blow the nucleus apart into its protons and neutrons, and often, if the neutrino's energy is quite high, also make some pions (another types of hadron: a particle made out of quarks, antiquarks and gluons like the proton and neutron). Recommended reading: Neutrino Oscillations for Dummies 17. The possible explanations again include oscillation into a sterile neutrino. The neutrino oscillation history.

Smirnov3),4)*** Received January 19, 2009 AbstractDespite the theory of neutrino oscillations being rather old, some of its basic issues are still being debated in the literature. SuperKamiokande has provided from atmospheric neutrinos the mixing angle 23 and the mass splitting m 23 2.The SNO measurements for the solar neutrinos clearly prefers the LMA solution, which fixes the range for 12 and . For an introduction to the subject see "Neutrino Oscillations for Dummies" by Chris Waltham, Am.J.Phys. A neutrino that does interact produces electrically charged particles that can produce a readily measurable signal in a transparent medium. By including a fourth neutrino with an appropriate value of m 4 1 2, flavor conversions mediated by the new state can occur more quickly than without it. 1. They oscillate, steal energy from stars, permeate through you all the time. The observations of neutrino oscillations, described in the next sections, can be accounted for by small mass dierencesm 12 andm 23, and large mixing angles 12 and 23.

(common materials for neutrino detectors). Neutrinos are generated in particle accelerators, in the sun, in other stars, and in nuclear reactions such as in nuclear reactors. In the late eighties several experiment claimed evidence for a neutrino mass of order 17 keV. The neutrino to antineutrino oscillation provides an indirect measurement of the effective Majorana neutrino mass, which would be different than that measured in the 0 experiment due to the additional phases introduced in propagation. Distinguishing long muon tracks from muon neutrino charged current interactions is as important. The existence of avour neutrino oscillations implies that if a neutrino of a given avour, say , with energy E is produced in some weak interaction process, at a suciently large distance L from the source the probability to nd a neutrino of a dierent avour, say , P( ;E,L), is dierent from zero.
