The Superconformal Xing Equation
Ilija Burić, Volker Schomerus, Evgeny Sobko
Crossing symmetry provides a powerful tool to access the non-perturbative dynamics of conformal and superconformal field theories. Here we develop the mathematical formalism that a…

Double-Scaling Limit in Principal Chiral Model: a New Non-Critical String?
Vladimir Kazakov, Evgeny Sobko, Konstantin Zarembo
We initiate a systematic, non-perturbative study of the large- expansion in the two-dimensional Principal Chiral Model (PCM). Starting with the…

Superconformal Blocks: General Theory
Ilija Buric, Volker Schomerus, Evgeny Sobko
In this work we launch a systematic theory of superconformal blocks for four-point functions of arbitrary supermultiplets. Our results apply to a large class of superconformal fiel…
