More recent experiments have detected additional anomalies in neutrino oscillations. The surprises in neutrino physics have not stopped with neutrino mass. But the discovery was a clear hint that understanding neutrinos may require new physics. Maybe the model can still be patched up-this is yet to be seen. This is a quantum mechanical effect that can only occur if neutrinos have mass, in contradiction to the current theories that describe fundamental particles and their properties, known as the Standard Model.
And over the past two decades, scientists have discovered an effect called neutrino oscillations, where neutrinos morph from one flavor to another. Neutrinos come in three types or flavors. But these elusive little wisps of matter may hold the key to the next major advance in our understanding of basic physics and the nature of the universe. And yet, even after multiple discoveries and three Nobel Prizes, scientists still know very little about them.
#A neutrino contains very little how to#
Scientists have known how to produce neutrinos in reactors and accelerators for more than 50 years. Neutrinos are a form of matter, but they interact with normal matter so rarely and so weakly that it’s hard to detect them.
They are everywhere-an estimated billion of them fill every cubic meter of space, and trillions more are emitted by our sun every second-but you can’t see them. Neutrinos are perhaps the most exotic particles known to science. Deep underground in Japan, this beam will be used to generate an intense source of neutrinos, whose behavior can then be measured precisely. The beam excites a small amount of air bled into the chamber, producing a glow that shows the presence of the particle beam.
