quantum field theory
In theoretical physics, quantum field theory (QFT) is a theoretical framework that combines Field theory (physics), field theory and the principle of relativity with ideas behind quantum mechanics. QFT is used in particle physics to construct phy ...

scattering amplitude
In quantum physics, the scattering amplitude is the probability amplitude of the outgoing spherical wave relative to the incoming plane wave in a stationary-state scattering process.
Formulation
Scattering in quantum mechanics begins with a p ...

In theoretical physics, a Feynman diagram is a pictorial representation of the mathematical expressions describing the behavior and interaction of subatomic particles. The scheme is named after American physicist Richard Feynman, who introduced ...
s. Richard Edwin Cutkowsky was born in Minneapolis as son of Oscar F. and Edna M. (Nelson) Cutkosky. His entire career was related to Carnegie, Pittsburgh, Pennsylvania. At the Carnegie Institute of Technology he made his Bachelor and Master of Science both in 1950, followed by a Doctor of Philosophy in 1953. 1954-1961 he was assistant professor of physics at the Carnegie Mellon University, professor since 1961 and the first Buhl professor since 1963 until his death in 1993.
[Buhl Lectures at the Carnegie Mellon University https://www.cmu.edu/physics/outreach/buhl-lect.html] He was a fellow of the American Physical Society and of the American Association for the Advancement of Science. He was married with Patricia A. Klepfer, August 28,1952. Children: Mark, Carol, Martha.
