Work
In decays of certain elementary particles, neutrinos are produced; particles that occasionally interact with matter to produce electrons. Melvin Schwartz, Leon Lederman, and Jack Steinberger managed to create a beam of neutrinos using a high-energy accelerator. In 1962, they discovered that, in some cases, instead of producing an electron, a muon (200 times heavier than an electron) was produced, proving the existence of a new type of neutrino, the muon neutrino. These particles, collectively called “leptons”, could then be systematically classified in families.
