Abstract:
Coleman and Weinberg (1973) gave the general formalism for computing quantum corrections to the effective potential, and showed how to renormalization-group improve the result. They discussed the case of a theory with a single scale. Effective field theory methods can be used to compute the potential in theories with multiple scales. There are some interesting new features which arise, which I will discuss in the talk.
The seminars start at 16:15 but the zoom meetings will be open already at 16:00.
