  1. 179. The $\gamma^* \gamma^*$ total cross section in NLA BFKL.
    Dr Dmitry Ivanov (Sobolev Institute of Mathematics)

    Progress in QCD
    We study the $\gamma^* \gamma^*$ total cross section in the NLA BFKL approach. We have extracted the NLO corrections to the photon impact factor from two recent papers of Balitsky and Chirilli and Chirilly and Kovchegov. Then use them to build several representations of the total cross section, equivalent within the NLA. We have combined these different representations with two among...

  2. 114. Unified BFKL and DGLAP evolution in terms of theta
    Prof. Alan Martin (IPPP, Durham)
    14/09/2014, 11:20
    Progress in QCD
    We present an evolution equation which simultaneously sums the leading BFKL and DGLAP logarithms for the integrated gluon distribution in terms of a single variable, namely the emission angle of the gluon. This form of evolution is appropriate for Monte Carlo simulations of events of high energy prton-proton interactions, particularly where small x events are sampled.

  3. 152. QCD mechanisms of (semi)exclusive Drell-Yan processes
    Prof. Oleg Teryaev (JINR)
    14/09/2014, 11:40
    Progress in QCD
    The (semi) exclusive pion-nucleon Drell-Yan processes with different non-perturbative QCD ingredients are considered. The classical one involves proton Generalized parton distribution (GPD) and pion distribution amplitude, while another one invloves proton and pion GPDs. For the first mechanism collinear factorization holds while for the second one the analytic continuation may be applied....

  4. 159. Double parton effects for jets with large rapidity separation
    Antoni Szczurek (Institute of Nuclear Physics, Krakow and Rzeszow University, Rzeszow)
    14/09/2014, 12:00
    Progress in QCD
    We discuss production of four-jet final state $pp \to jjjjX$ in proton-proton collisions at the LHC through the mechanism of double-parton scattering (DPS) in the context of jets with large rapidity separation. The DPS contributions are calculated within the so-called factorized Ansatz and each step of DPS is calculated in the LO collinear approximation. The LO pQCD calculations...

  5. 118. On effects of multiple gluons in J/psi hadroproduction
    Mariusz Sadzikowski (Jagiellonian University)
    14/09/2014, 12:20
    Progress in QCD
    Prompt J/psi hadroduction is considered beyond the leading twist two-gluon production mechanism. A contribution to the process is analysed in which the meson production is mediated by three-gluons, with two gluons coming from the target and one gluon from the projectile. Such contribution is enhanced at large energies due to large double gluon density at small x. This contribution is...
