Wilson lines as superconformal defects for ABJM theory

by Dr. Lorenzo Bianchi (Hamburg University)

Tuesday, 5 December 2017 from to (Europe/Rome)
at Dipartimento di Fisica e Astronomia ( Aula Teorici )
Via Irnerio, 46
Description
In this talk we analyse the consequences of interpreting Wilson lines as superconformal defects for the specific case of ABJM theory. We will show that this interpretation allows to derive a previously conjectured formula for the energy emitted by an accelerating heavy particle. This formula leads (in principle) to an exact computation via localization techniques. In the end of the talk, we will also discuss the surprising relation between the emitted radiation and the stress tensor one-point function and briefly mention the appearance of similar relations in apparently unrelated contexts.
