dc.descriptionThe differential cross section for the dilepton production is calculated including Fermi motion of hadron constituents as well as emission from the ladders in the formalism of unintegrated parton distributions. We use unintegrated parton distributions which fulfil Kwieciński evolution equations. Both zeroth- and first-order (for matrix element) contributions are included. We calculate azimuthal angular correlations between charged leptons and deviations from the $p_t(l^+) = p_t(l^-)$ relation. We concentrate on the distribution in dilepton-pair transverse momentum. We find incident energy and virtuality dependence of the distribution in transverse momentum of the lepton pair. We study also azimuthal correlations between jet and dilepton pair and correlation in the $(p_{1t}(jet),p_{2t}(l^+ l^-))$ space. The results are compared with experimental data of the R209 and UA1 collaborations.
