s-channel, t-channel and the u-channel processes for both the equal and unequal masses of participating particles. The conditions for the occurrence of these channel processes have been made explicit through the Mandelstam plot. Introducing scattering amplitude as the matrix element of S-matrix, the crossing and Bose symmetries of scattering amplitudes for s-, t-, u-channel scatterings have been explained and the analyticity of scattering amplitude has been elucidated through examples.
The topic Regge poles, describes the study of resonances and Regge poles that can be undertaken through the scattering process. Due to the significant role of partial waves in the chapter, the scattering process has been explained through the partial wave analysis and the scattering cross section has been expressed in terms of scattering amplitude and by the optical theorem.
Assignments have been given at the end of each chapter, which contain descriptive questions as well as problems. A new feature of the book is that it has a substantial number of objective type questions to help aspirants of GATE, NET and related examinations.
Most of the topics forming the model syllabus of University Grants Commission for Post Graduate Particle Physics (III Semester), Nuclear and Particle Physics (IV Semester, Strong, Weak and Electromagnetic Interactions) and Quantum Electrodynamics have been covered in the book. The topics have been developed in a pedagogical manner by providing all possible algebraic details.
