Share to Facebook. Neutrinos are generated in particle accelerators, in the sun, in other stars, and in nuclear reactions such as in nuclear reactors. 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. The discovery of neutrino oscillations opened a new era in neutrino physics: an era of investigation of neutrino masses, mixing, magnetic moments and other neutrino properties. This book explains the physics and phenomenology of massive neutrinos. In order to help with the pedagogical diculties this poses, I attempt here to present the physics in words and pictures rather than math. Deep beneath the earth's surface, in mountain tunnels, Antarctic ice, and abandoned zinc and gold mines, physicists search for the elusive 'ghost particle' known as neutrino.Spat out of supernovas, colliding galaxies, and the Big Bang itself, about 100 trillion of these ghostly subatomic entities careen through our bodies at nearly the speed of light every second, going unnoticed because .

Neutrinos are teeny, tiny, nearly massless particles that travel at near lightspeeds. Most neutrinos zoom right through matter, leaving no detectable presence. It depends on the energy of the neutrino. 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. LANSCE: Unique capabilities for science and national . They are generated whenever there is a nuclear reaction in the form of beta decay. The hypothetical particle may constitute an important part of dark matter, a prospective form of matter thought to make up the vast majority of the physical universe. (Submitted on 28 Mar 2003) Abstract:The reality of neutrino oscillations has not really sunk in yet. We are not allowed to display external PDFs yet. electron-neutrinos or muon-neutrinos) consist of a superposition of two or more masses. All you need to know is in this one short equation: (Source: einstein-schrodinger.com) Wait, don't run away, I was just joking! Neutrino oscillations are the best explanation, at the same time, of the Solar Neutrino puzzle and for the azimuthal variation of the atmospheric muon neutrino flux.
