Theoretical Developments

Recent theoretical developments to calculate cross sections of hadronic objects in the high energy limit are summarised and experimental attempts to establish the need for new QCD effects connected with a resummation of small hadron momentum fractions x are reviewed. The relation between small-x parton dynamics and the phenomenon of diffraction is briefly out-lined. In addition, a search for a novel, non-perturbative QCD effect, the production of QCD instanton induced events, is presented.

Near Future

We have shown that, provided that the nonperturbative input is regular at the right of the ω=0 singularity of the dominant DGLAP anomalous dimension, the rise of F2 at small x, experimentally measured by the averaged observable [Formula: see text], is input-independent in the perturbative Q2 regime at small x. [Formula: see text] appears to be more input-dependent in the same range. The GRV-type parametrizations verify these properties. Other models, namely the BFKL kernel (QCD dipoles), DGLAP (with a nonperturbative input singular at the right of the ω=0) give different predictions for λ. At moderate Q2, there is a possibility of distinguishing these different perturbative QCD predictions in the near future.

A brief review of key recent developments and ongoing projects in perturbative QCD theory, with emphasis on conceptual advances that have the potential for impact on LHC studies. Topics covered include: twistors and new recursive calculational techniques; automation of one-loop predictions; developments concerning NNLO calculations; the status of Monte Carlo event generators and progress in matching to fixed order; analytical resummation including the push to NNLL, automation and gap between jets processes; and progress in the understanding of saturation at small x.
