Crossing Symmetry for Long Multiplets in 4D SCFTs
Ilija Buric, Volker Schomerus, Evgeny Sobko
In this work we construct the crossing symmetry equations for mixed correlators of two long and two BPS operators in 4D SCFTs. The analysis presented here illustrat…
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…
