The revolution in elementary particle physics sparked by the unearthing of the
bizarre J/'Y particle in 1974 and followed by the discovery of the equally myste-
rious -r and T particles, led to a beautiful interweaving of theory and experiment
culminating in the Salam-Weinberg theory of electroweak interactions and the
quantum chromodynamic (QCD) theory of strong interactions. The extraordi-
nary prediction of the W and Z° bosons was fulfilled in 1983, and it is now
possible to produce Z° in millions. The emphasis today is on refined testing of
the detailed quantitative predictions of the theories, and, to match this, more
sophisticated calculations are demanded. This book presents, in two volumes,
prehensive and unified treatment of modern theoretical and experimental
particle physics at a level accessible to beginning research students. The empha-
sis throughout is on presenting underlying physical principles in a simple and
intuitive way, and the more sophisticated methods demanded by present-day
research interests are introduced in a very gradual and gentle fashion.
Volume 1 covers electroweak interactions, the discovery and properties of the
`new' particles, the discovery of partons and the construction and predictions
of the simple parton model. Volume 2 deals at some length with CP violation,
but is mainly devoted to QCD and its application to `hard' processes. A brief
coverage of soft hadronic physics and of non-perturbative QCD is included.
This work will provide prehensive reference and textbook for all graduate
students and researchers interested in modern particle physics.
