actions between elementary particles mediated, or carried, by W and Z particles and that are responsible for nuclear decay. Weak interactions are one of four fundamental interactions in nature, the others being gravitation, electromagnetism, and the strong interactions.

[Ital.,=little neutral (particle)], elementary particle with no electric charge and a very small mass emitted during the decay of certain other particles. The neutrino was first postulated in 1930 by Wolfgang Pauli in order to maintain the law of conservation of energy

Steinberger, Jack(1921– ) physicist; born in Bad Kissigen, Germany. He fled the Nazis with his brother and came to the U.S.A. in 1935. After performing research at Princeton (1948–49) and the University of California: Berkeley (1949–50), he joined Columbia University (1950–72). He, L. Lederman, and M. Schwartz shared the 1988 Nobel Prize for their 1960–62 accelerator-created beam of neutrinos and subsequent discovery that neutrinos exist in two types. Steinberger continued his subatomic particle research at the European Organization for Nuclear Research (CERN) (1968–86), then became a professor at the Scuola Normale, Pisa (1986).
