Abstract:
This is a series of 12 introductory lectures on Regge Poles and their role in high-energy diffraction scattering, during the academic year 1962-1963. Lecture I is a general introduction to the idea of complex angular momentum. Lectures II to V give an account of Regge's original work on Potential scattering. Lectures VI to IX deal with high-energy diffraction scattering. Lecture X gives an account of the extension of the Regge Representation proposed by Mandelstam. The Conjectures by Frautschi, Gell-Mann and Zacharisen - on carrying over the results of potential scattering to a relativistic theory are discussed in detail in the Lecture XI.
