Major Academic Achievements

In 1961, Glashow extended electroweak unification models due to Schwinger by including a short-range neutral current, the Z0. The resulting symmetry structure that Glashow proposed, SU (2) × U (1), forms the basis of the accepted theory of the electroweak interactions. For this discovery, Glashow along with Steven Weinberg and Abdus Salam, was awarded the 1979 Nobel Prize in Physics.

In 1964, in collaboration with James Bjorken, Glashow was the first to predict a fourth quark, the charm quark. The prediction of the charm quark also removed a technical disaster for any quantum field theory with unequal numbers of quarks and leptons.

In 1973, Glashow and Howard Georgi proposed the first grand unified theory. This work was the foundation for all future unifying work.
