Maths HEP Lunchtime Seminars: What are Color Twist Operators, and why they are good for Integrability

Presented by Andrea Cavaglia', King's College London

18 October 2019 13:00 in CM101

I will present the definition of a deformation of local operators (called Color Twist Operators) in a large N theory.
This construction allows to break in a controlled way the symmetries of correlators, including spacetime symmetries.
I will explain why, in integrable higher-dimensional CFTs such as N=4 supersymmetric Yang-Mills theory, this deformation
is expected to be very useful to compute correlators at finite coupling.
Some examples will be presented, concentrating on N=4 SYM and on a related integrable CFT with no supersymmetry known
as the Fishnet theory.
The talk is based on works in progress with D. Grabner, N. Gromov, F. Levkovich-Maslyuk and A. Sever.
