What is Elementary Particles and Their Currents about?

The plan of the book is as follows. The first chapter contains a brief review of the elements of field theory, especially of the free fields. Apart from fixing conventions on the Lorentz metric and the like, a sophisticated reader will not learn much by reading it. In Chapter 2 the currents are introduced in a general way and the connection between current conservation and an invariance group is illustrated with the classical case of the group of invariances of a Lagrangian containing two degenerate scalar fields the group SU2. Although this chapter deals only with free fields we use throughout the LSZ technique for constructing one-particle states via the asymptotic condition. The formulas are then easily generalized to the interacting field case, and, in fact, the third chapter deals with SU2 in the context of interacting pion-nucleon fields. In the fourth chapter we turn on the electromagnetic field and study SU2 as a "broken symmetry." With Chapter 5 the real work of the book gets underway. Here we begin the study of electron-proton scattering. As the reader will discover, there is a detailed analysis of the form factor structure of the matrix elements of the currents as they a
