Triple-pomeron amplitude in the effective action approach

Abstract

Abstract In the effective action approach the imaginary part of the triple pomeron amplitude is calculated. The found dependence on the longitudinal momentum transfer $$e_{-}$$ e- is found to separate as a simple factor $$1/|e_{-}|$$ 1/|e-| . This result is used to calculate the high-mass diffraction on a hadron and double scattering cross-section off a composite target.
