The parton model, electromagnetic form factors of hadrons and high energy elastic π±p scattering

Abstract

Following the idea of Wu and Yang (1965) that the electromagnetic and nuclear distributions behave similarly at large momentum transfer, the author has studied the differential cross section for pi +or-p elastic scattering at high energy within the framework of the parton model. By using the idea of Drell and Yan (1970) he has calculated the electromagnetic form factors of the pion and proton and they are shown to decrease as t-1 and t/2-2 respectively at large t.
