Current and Mesons is the most recent publication in the Chicago
Lectures in Physics series. The book presents Professor Sakurai's
introduction to a new field of elementary particle physics which has
become increasingly important in the past few years. It is based on a
course given to his advanced graduate students in theoretical
high-energy physics at the University of Chicago.
The author begins with a brief review of SU (3). The major topics then
treated are the divergence condition and current commutation relations,
vector meson universality, PCAC and the Goldberger-Treiman relation,
soft pion processes, and asymptotic symmetries and spectral-function sum
rules. The book concludes with a discussion of notation and of
normalization convention.
Professor Sakurai's work deals with topics on which much of current
discussion on the theory of elementary particles is focused. The
material is designed for the advanced student who is seriously
interested in doing original work, and as such provides a much needed
introduction to the present literature in the field.
