Relativistic Quantum MechanicsIn this text the authors develop a propagator theory of Dirac particles, photons, and Klein-Gordon mesons and per-form a series of calculations designed to illustrate varioususeful techniques and concepts in electromagnetic, weak, andstrong interactions. these include defining and implementingthe renormalization program and evaluating effects of radia-tive corrections, such as the Lamb shift, in low-ordercalculations. The necessary background for the book is pro-vided by a course in nonrelativistic quantum mechanics atthe general level of Schiff's text, QUANTUM MECHANICS. |
