Structure constants of twist-two light-ray operators in the triple Regge limit

Abstract

Abstract The structure constants of twist-two operators with spin j in the BFKL limit g 2 → 0, j → 1 and $$ \frac{g^2}{j-1} $$ g 2 j − 1 ∼ 1 are found from the calculation of the three-point correlator of twist-two light-ray operators in the triple Regge limit. It is well known that the anomalous dimensions of twist-two operators in this limit are determined by the BFKL intercept. Similarly, the obtained structure constants are determined by an analytic function of three BFKL intercepts.
