This comprehensive and well-organized book focusses on the phenomeno-logical aspects of Particle Physics. It strikes a fine balance between those texts that require sophisticated mathematical physics and those that are too elementary. For, unlike in many books on the subject, which give prominence to gauge theories, the attempt here is to lay stress on phenomenology _ an aspect that needs exposure among students of high energy physics.
In this text, Professor Khanna, with his wealth of experience and expertise, gives a masterly analysis of such topics as symmetries, quark model, current concepts of gauge theories, the standard model, and flavour physics. He also highlights the role that currents have played in electromagnetic and weak interactions, and of nonleptonic weak decays in weak interactions. Finally, he provides an adequate coverage of heavy quark physics, which is so timely for prospective high energy physicists, and deals with the recent developments. Designed as a one-semester/one-year course on Particle Physics at the postgraduate level and as a first reading for research students, the book should prove both useful and stimulating.
