Effects of Quark-Pomeron Coupling Structure in Diffractive Deep Inelastic Scattering

Abstract

We study the contribution of diffractive $Q\bar{Q}$ production to the $F_2^D$ proton structure function and the longitudinal double-spin asymmetry in polarized deep--inelastic $lp$ scattering. We show the strong dependence of the $F_2^D$ structure function and the $A_{ll}$ asymmetry on the quark--pomeron coupling structure.
