The last few decades have seen major advances in the physics of elementary particles. New generations of particle accelerators and detectors have come into operation， and have successfully contributed to improving the quantity and quality of data on diverse interaction processes and to the discoveries of whole new families of particles. At the same time， important new ideas have emerged in quantum field theory， culminating in the developments of theories for the weak and strong interactions to complement quantum electrodynam-ics， the theory of the electromagnetic force. The simplest of the new theories that are at the same time mathematically consistent and physically successful constitute what is known as the standard model of the fundamental interac-tions. This book is an attempt to present these remarkable advances at an elementary level， making them accessible to students familiar with quantum mechanics， special relativity， and classical electrodynamics.
