Introduction to Relativistic Processes and the Standard Model of Electroweak Interactions

Carlo M. Becchi is full professor in Theoretical Physics at the University of Genoa since 1976. He is an expert in quantum gauge theories and renormalization, he is one of the discoverers of the Becchi-Rouet-Stora transformation which is now a basic tool for the quantization of systems with constraints. Carlo M. Becchi is Supervisory Editor of Nuclear Physics B. Giovanni Ridolfi received his doctorate in physics from University of Genoa, Italy, in 1989, and has held research appointments at CERN, Geneva and at the italian Istituto Nazionale di Fisica Nucleare. He is now full Professor of Theoretical Physics at the University of Genoa, Italy. His research interests are in the field of phenomenology of fundamental interactions.
