On the Regge limit of Fishnet correlators

Blog Article

Abstract We study the Regge trajectories of the Mellin amplitudes of the 0-,1- and 2-magnon correlators of the Fishnet theory.Since fishnet theory is both integrable and conformal, the correlation functions Plastic Pipes are known exactly.We find that while for 0 and HOPS 1 magnon correlators, the Regge poles can be exactly determined as a function of coupling, 2-magnon correlators can only be dealt with perturbatively.We evaluate the resulting Mellin amplitudes at weak coupling, while for strong coupling we do an order of magnitude calculation.
