The muon neutrino is a subatomic lepton elementary particle which has the symbol and no net electric charge. Together with the muon it forms the second generation of leptons, hence its name ''muon neutrino''. It was first hypothesized in the early 1940s by several people, and was discovered in 1962 by Leon Lederman, Melvin Schwartz and Jack Steinberger. The discovery was rewarded with the 1988 Nobel Prize in Physics. ==Discovery== In 1962 Leon M. Lederman, Melvin Schwartz and Jack Steinberger established by performing an experiment at the Brookhaven National Laboratory〔 〕 that more than one type of neutrino exists by first detecting interactions of the muon neutrino (already hypothesised with the name ''neutretto''〔 〕), which earned them the 1988 Nobel Prize.〔 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Muon neutrino」の詳細全文を読む スポンサード リンク
