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

Abstract

The structure constants of twist-two operators with spin $j$ in the BFKL limit $g^2\to 0,j\to 1$ but $\frac{g^2}{j-1}\sim 1$ are determined 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.
