On Monday, April 7, I gave a lecture on “Neutrino Mysteries” to the Osher Lifelong Learning Institute of UC Irvine. It is at the link Neutrino Mysteries 5 .
The talk covers neutrino properties and an explanation of neutrino mixing. It also shows how the flavor neutrinos associated with the electron, muon, and tau leptons are composed of superpositions of neutrinos with definite mass. The talk also covers the origin of neutrinos in nuclear reactors, in the sun, in the atmosphere, and in supernova. The simplified model of the neutrino mixing matrix is discussed.
The first lecture for the course contained the YouTube video Project Poltergeist by the BBC Horizon Project. It was about the discovery of the deficit in electron neutrinos from the sun by Ray Davis, compared to the solar model calculations of John Bachall.
