Modern renormalization and collider physics
Winter, 2008, TIFR
Part A: Renormalization and effective theories
Renormalization and renormalization group flows; effective long distance theories. A solvable example to illustrate the notions of ultraviolet cutoff, fixed points, stability of low-energy scattering matrix elements, bound state energies, non-trivial scaling etc.
Effective theory of QED: the Euler-Heisenberg action. Axions: how to include unknown physics into effective theories. Applications to astrophysics. Effective theories of modified gravity.
Part B: Application to colliders
