ITMP Seminar "Surface operators in the 6d N=(2,0) theories"

ITMP Seminar
8 ноября 2021

Dear Colleagues,

We are pleased to announce that the next internal ITMP seminar will be held on Wednesday, Nov 10, at 18:00 (Moscow time). It will take place in ITMP, in person, room Г-725. It will be also possible to participate online via zoom


Speaker: Dr. Maxime Trepanier, ITMP

Title: Surface operators in the 6d N=(2,0) theories

Abstract: One of the surprising predictions of string theory is the existence of QFTs in 6d with superconformal symmetry known as the 6d N=(2,0) theories. These theories contain surface operators which are analogous in many ways to Wilson loops in gauge theories. In this talk I will discuss some of the properties of these operators that make them ideal observables to learn about the 6d N=(2,0) theories. After reviewing the simplest example (the sphere) both in field theory and in holography, I will discuss how supersymmetry helps to find the holographic description for more complicated surface operators. In particular, in my recent work we found the holographic description for a class of tori, and their expectation value captures a 6d analog of the quark-antiquark potential.


If you want to join the seminar please register here before 14:00, November 10  here.
