•Lack
of solar neutrinos confirmed by Kamiokande II detector in Japan. (Using different detection method)
•
•Possible
explanation in terms of Neutrino physics
–3
different types of Neutrinos:
•electron, muon, and tau neutrinos
•Sun
generates and Cl detectors see only electron neutrinos
•Can
electron neutrinos can change to another type on way here?
–These
“neutrino oscillations” are possible if neutrino has non-zero
mass
–
–Kamiokande
II evidence of muon neutrinos becoming electron ones

•Neutrino
mass may have implications for “cosmology”
•Neutrinos
