“Fun with regularization and renormalization“
Abstract:
The history of regularization and renormalization is full not only of important
breakthroughs and fundamental theorems but also of puzzles and paradoxical,
inconsistent, or wrong results. Many issues have been clarified in the past years,
leading to interesting conceptual insights into quantum field theory and to results
of practical importance. The talk will first focus on variants of dimensional
regularization, give a brief overview of the historical development and provide
a precise definition of all schemes and their differences. New results regarding
the infrared structure of QCD and regarding supersymmetry-preserving
regularizations will be explained.
Then the talk will focus on the renormalization of gauge theories. The role of
Slavnov-Taylor identities as tools will be explained. As an application, the
renormalization properties, gauge dependence and beta functions of vacuum
expectation values will be derived.
