  1. 137. Euler-Lagrange equations for effective actions in QCD and gravity at high energies
    Lev Lipatov (Petersburg Nuclear Physics Institute)

    Progress in QCD
    The high energy asymptotics of scattering amplitudes in QCD is formulated in terms of reggeized gluons and their interactions. I remind the functional approach for the calculation of various reggeon vertices. The Euler-Lagrange equations for the corresponding effective action allows to find the reggeon field theory in QCD in tree approximation. The simplest composite state of Reggeized...

  2. 138. Reggeon field theory as an effective theory for QCD at high energies
    Joachim Bartels (University Hamburg)
    05/09/2016, 09:20
    Progress in QCD
    Based upon an analysis of the renormalization flow equations we analyse the fixed point structure and derive a new scaling law solution. Particular emphasis is given to the transverse extension of the scattering amplitude.

  3. 143. Peculiarities of the BFKL approach in the NNLLA
    Victor Fadin (Institute of Nuclear Physics SB RAS)
    05/09/2016, 09:40
    Progress in QCD
    Peculiar properties of the BFKL approach in the next-to-next-to-leading logarithmic approximation are discussed. In this approximation the scheme of derivation of the BFKL equation must be changed because of violation of the simple factorized form of amplitudes with multi-reggeon exchanges.

  4. 117. Pomeron-Odderon interactions: a functional RG flow analysis
    Gian Paolo Vacca (BO)
    05/09/2016, 10:00
    Progress in QCD
    An effective field theory for interacting pomeron and odderon fields is studied non perturbatively analysing the flow of the effective average action. We present some preliminary results on the critical structure associated to the fixed points of the flow.

  5. 115. Di-hadron production at LHC: BFKL predictions for cross sections and azimuthal correlations
    Francesco Giovanni Celiberto (CS)
    05/09/2016, 10:20
    Progress in QCD
    A study of the inclusive production of a pair of hadrons (a “di-hadron” system), having high transverse momenta and separated by a large interval of rapidity, is presented. This process has much in common with the widely discussed Mueller-Navelet jet production and can be also used to access the BFKL dynamics at proton colliders. Large contributions enhanced by logarithms of energy can be...
