Theory of Fundamental Interactions 1

The course aims at providing an understanding of the basics of quantum field theory, and of the techniques applied for the calculation of physical processes at high energies.

At the end of the course the student will be able to: 1. describe the
quantization procedure for the electromagnetic field, for the scalar field and for the Dirac field; 2. describe the kinematics of a physical process of interaction between particles (phase space, reference system, Mandelstam invariants); 3. calculate the cross section at tree level starting from the Feynman rules of QED; 4. set up a calculation with one or more loops and understand the meaning of the procedure for the
renormalization the ultraviolet singularities and for the cancellation of the infrared singularities.
