New Old Renormalization
- Kang-Sin Choi (Ewha Womans University)
Description
Abstract: We present a new view of renormalization: it is a reorganization of physical quantities in terms of observables in effective field theory. This enables us to understand the meaning of what were previously regarded as technicalities: naturalness, gauge symmetry, regularization and scheme dependence. In particular, we apply it to the scalar mass to illustrate its power-law running and shed light on the hierarchy problem.
