Stanley Mandelstam

Professor Stanley Mandelstam FRS


Elected: 1962


Stanley Mandelstam is well known for his important contributions to quantum field theory. He initiated and developed the treatment of scattering amplitudes as analytic functions of two variables and proposed the double dispersion relation which came to dominate 1960s thought about reactions between elementary particles. In collaboration with others, he contributed much to the application of these ideas, in particular to the mutual scattering of pi mesons.
