摘要
A dipole picture of high energy scattering is developed in (2+1)-dimensional QCD, following Mueller. A generalized integral equation for the dipole density with a given separation and center of mass position is derived, and the meson-meson nonforward scattering amplitude is therefore calculated. We also calculate the amplitude due to two-Pomeron exchange, and the triple-Pomeron coupling. We compare the result obtained by this method to our previous result based on an effective action approach, and find the two results agree at the one-Pomeron exchange level. © 1995 The American Physical Society.
