Quark-Antiquark Production in DIS Diffractive Dissociation

Abstract

We calculate the cross section for the production of two jets with large transverse momenta ${\text{kf}}^2$ in DIS diffractive dissociation for both transverse and longitudinally polarized photons. The scale which defines the hardness of the pomeron is found to be ${\text{kf}}^2\frac{Q^2+M^2}{M^2}$. We present analytic expressions and discuss numerical results relevant for the diffractive dissociation at HERA.
