- Purpose of the course: to provide an introduction to the standard model of particle interactions and make the student familiar with its phenomenological consequences at leading order in perturbation theory; to equip the students with analytical and numerical skills and techniques to carry out computations of decay rates and cross sections at leading order in perturbation theory.
