Abstract
We study the Feynman graph structure and compute certain exact four-point correlation functions in chiral CFT4 proposed by Ö. Gürdŏgan and one of the authors as a double scaling limit of γ-deformed mathcal{N}mathrm{Unknown} mathrm{character} left(0mathrm{x}mathrm{F}700right) mathrm{from} "mathrm{Euclid} mathrm{Math} mathrm{One}" left(0mathrm{x}3mathrm{D}right) = 4 SYM theory. We give full description of bulk behavior of large Feynman graphs: it shows a generalized “dynamical fishnet” structure, with a dynamical exchange of bosonic and Yukawa couplings. We compute certain four-point correlators in the full chiral CFT4, generalizing recent results for a particular one-coupling version of this theory — the bi-scalar “fishnet” CFT. We sum up exactly thecorresponding Feynman diagrams, including both bosonic and fermionic loops, by Bethe-Salpeter method. This provides explicit OPE data for various twist-2 operators with spin, showing a rich analytic structure, both in coordinate and coupling spaces.
