Description

In this measurement, the cross section for dijet production in diffractive deep-inelastic scattering is presented. The diffractive events are selected by requiring the presence of a Large Rapidity Gap in the forward region of H1 detector. The data have been collected during the HERA-2 period and correspond to an integrated luminosity of 284 pb$^{-1}$. The data cover the range x_P <0.03 and 4 ≤ Q$^{2}$ ≤ 80 GeV$^{2}$ in photon virtuality. The phase space of the analysis is defined by two inclusive jets found by the k_T cluster algorithm in the hadronic centre-of-mass system. The leading and sub-leading jets are required to have E_T$^{*jet1}$ > 5.5 GeV and E_T$^{*jet2}$ > 4 GeV, respectively and to lie within LAr calorimeter acceptance, i.e. -1 < η$^{jet1,2}$ < 2. Differential cross sections are compared to QCD Next-to-leading calculations corrected to the level of stable hadrons.
