Quantum anomalies correspond to the
breaking of certain symmetry properties by the quantization procedure
in field theory. The initial indication of quantum anomaly was recognized
immediately after the birth of modern quantum theory, namely, renormalization
theory, but its true physical significance was fully recognized only
in 1969. Since then, quantum anomalies have become one of the most
profound and important notions of modern field theory. Quantum anomalies
played prominent roles not only in the establishment of the Standard
Model of elementary particles, but also in the recent development
in string theory. At this moment, quantum anomalies are classified
into two basic categories, chiral anomaly and Weyl (or conformal)
anomaly.
In this monograph, a path integral approach to quantum anomalies,
which was initiated by the author and developed later by the efforts
of many people, is presented in a coherent manner. In the path integral
approach, all the known quantum anomalies are identified as non-trivial
Jacobian factors under the relevant symmetry transformations of path
integral variables. This approach provides a unified view of the symmetry
breaking phenomena by quantization procedure itself. It also provides
a transparent picture for the topological aspects of quantum anomalies,
which are related to the Atiyah-Singer index theorem and the Riemann-Roch
theorem. Path integral approach also proved to be useful recently
in the treatment of chiral anomaly in lattice gauge theory and the
bosonization of Abelian and non-Abelian models in two-dimensional
theory. A coherent treatment of the path integral method is presented
in this book starting with an elementary account of Feynman path integral
and Schwinger's action principle. This book is aimed to be accessible
to readers with a basic knowledge of quantum theory at the level of
beginning graduate students. |
