This volume contains the lecture notes of the VI J A S Summer School. The topics covered are particle physics phenomenology, dynamical symmetry breaking, conformal theory.

This book contains the proceedings of the IXth Jorge André Swieca Summer School — Particles and Fields — held at Campos do Jordao in February 1997.It surveys some of the most interesting research topics in theoretical physics, like duality theory, quantum field theory in curved space-time, supersymmetry and the standard model, differential geometry and its applications in physics and cosmic ray physics.

This book constitutes the proceedings of the X Jorge André Swieca Summer School — Particles and Fields. It includes topics on non-commutative geometry, constructive quantum field theory and duality in quantum field theory, as well as various subjects in high energy physics and phenomenology.

The J. A. Swieca Summer School series is organized by the Brazilian Physics Society. The VIII school was dedicated to topics in astrophysics, chaos, nuclear structure and reactions, and to QCD in nuclear physics.

They were musicians, writers, painters, actors, scientists, mathematicians, architects, doctors, photographers, dancers, businessmen and even circus clowns, police officers and football coaches. All refugees from nazi fascism, who sought salvation from 1933 onwards. They are remembered in 300 illustrated biographies, representing the thousands of fugitives who made or remade their lives and careers in Brazil and contributed so much to Brazilian society. Each trajectory, an epic, from birth and training in the Old World, the terrible dangers and sufferings faced with the arrival of Nazism, the struggles and adventures to escape, obtain visas and embark towards freedom. The Dictionary of Refugees from Nazi fascism in Brazil reports all this. It is yet another publication by Casa Stefan Zweig, based in Petrópolis and dedicated to the dissemination and study of the work of the great Austrian writer who died here and the role of refugees who, like him, escaped from the totalitarianism.

The lecture notes in this proceedings present an introductory and updated review of some of the current topics of interest in theory and phenomenology of the strong and electroweak interactions.
