Melvin Schwartz

Melvin Schwartz (1932–2006) was an American experimental physicist who shared the 1988 Nobel Prize in Physics for demonstrating that the muon neutrino is distinct from the electron neutrino.

Leon Lederman: Leon Lederman was an American physicist who shared the 1988 Nobel Prize in Physics for neutrino research. He collaborated with Schwartz and Jack Steinberger on the experiment that identified the muon neutrino.
Muon neutrino: The muon neutrino is an elementary particle associated with the muon and one of the three known neutrino flavors. Schwartz's experiment showed that neutrinos produced with muons could create muons rather than electrons.
Lepton: A lepton is an elementary particle that does not experience the strong nuclear force. The muon neutrino joined the electron neutrino as a distinct member of the lepton family.
Neutrino: A neutrino is a neutral, extremely light elementary particle that interacts through the weak force and gravity. Theoretical and experimental work on neutrinos set the stage for testing whether they had distinct flavors.
Jack Steinberger: Jack Steinberger was a German-American physicist who shared the 1988 Nobel Prize in Physics for neutrino research. He joined Schwartz and Lederman in carrying out the neutrino experiment at Brookhaven.
Brookhaven National Laboratory: Brookhaven National Laboratory is a United States research center on Long Island, New York. Its Alternating Gradient Synchrotron supplied the energetic proton beam for the experiment.
Standard Model: The Standard Model is the theory describing known elementary particles and their electromagnetic, weak, and strong interactions. The confirmed muon neutrino became one of the model's three neutrino flavors.
Muon: A muon is an elementary particle similar to an electron but heavier and unstable. Pontecorvo's proposed test used the association between muons and a distinct neutrino type.
Bruno Pontecorvo: Bruno Pontecorvo was an Italian-born physicist who proposed that neutrinos produced with muons could be distinguished from other neutrinos. His proposal inspired the experiment Schwartz and his collaborators designed.
Pion: A pion is a meson composed of a quark and an antiquark, with charged and neutral forms. Pions created by the proton beam decayed into muons and neutrinos for the test.
