N2 - We studied the ep→ep+2 jets diffractive cross section with ZEUS phase space. Neglecting the t-channel momentum in the Born and gluon dipole impact factors, we calculated the corresponding contributions to the cross section differential in β=Q2Q2+M2 jets2 and the angle φ between the leptonic and hadronic planes. The gluon dipole contribution was obtained in the exclusive kt-algorithm with the exclusive cut ycut=0.15 in the small ycut approximation. In the collinear approximation we canceled singularities between real and virtual contributions to the qq̄ dipole configuration, keeping the exact ycut dependency. We used the Golec-Biernat-Wüsthoff (GBW) parametrization for the dipole matrix element and linearized the double dipole contributions. The results give roughly 12 of the observed cross section for small β and coincide with it for large β.
