A neutrino walks into a bar…" As reports spread of subatomic particles moving faster than light and potentially travelling through time, such gags were born. But apparently super-hasty motion is not the only strange thing about neutrinos. Neutrino oscillation. Observations[edit] A great deal of evidence for neutrino oscillation has been collected from many sources, over a wide range of neutrino energies and with many different detector technologies.[2] Solar neutrino oscillation[edit] The first experiment that detected the effects of neutrino oscillation was Ray Davis's Homestake Experiment in the late 1960s, in which he observed a deficit in the flux of solar neutrinos with respect to the prediction of the Standard Solar Model, using a chlorine-based detector.

Neutrino oscillation

This gave rise to the Solar neutrino problem. Many subsequent radiochemical and water Cherenkov detectors confirmed the deficit, but neutrino oscillation was not conclusively identified as the source of the deficit until the Sudbury Neutrino Observatory provided clear evidence of neutrino flavor change in 2001. #63: Ghost Particles Shake Physics.
