Octagon with finite bridge: free fermions and determinant identities
Ivan Kostov, Valentina B. Petkova
We continue the study of the octagon form factor which helps to evaluate a class of four-point correlation functions in SYM theory. The octagon is characterised, be…
The Octagon as a Determinant
Ivan Kostov, Valentina B. Petkova, Didina Serban
The computation of a certain class of four-point functions of heavily charged BPS operators boils down to the computation of a special form factor - the octagon. In this paper, whi…
Determinant formula for the octagon form factor in =4 SYM
Ivan Kostov, Valentina B. Petkova, Didina Serban
We compute to all loop orders correlation function of four heavy BPS operators in = 4 SYM with special polarisations considered recently by Frank Coronado. Our main re…
On some Coulomb gas integrals in higher dimensions
P. Furlan, V. B. Petkova
We point out that there is a generalization to higher dimensions of the two-dimensional Dotsenko-Fateev formula \DF\ for particular Coulomb gas conformal invariant integra…
Toda example as hidden Liouville CFT
P. Furlan, V. B. Petkova
We construct correlators in the Toda 2d conformal field theory for a particular class of representations and demonstrate a relation to a (Virasoro) theory with differen…
On some 3-point functions in the CFT and related braiding matrix
P. Furlan, V. B. Petkova
We construct a class of 3-point constants in the Toda conformal theory , extending the examples in Fateev and Litvinov. Their knowledge allows to determine the braidin…
