Heavy quark impact factor in kT-factorization

We present the calculation of the finite part of the heavy quark impact factor at next-to-leading logarithmic accuracy in a form suitable for phenomenological studies such as the calculation of the cross-section for single bottom quark production at the LHC within the kT-factorization scheme.

Saturation and coherence effects in the modified KGBJS equation

We solve the modified non-linear extension of the CCFM equati on KGBJS equation numerically for certain initial conditions and compare the resulting gl uon Green functions with those obtained from solving the original CCFM equation and the BFKL and BK equations for the same initial conditions. We improve the low transversal momentum behaviour of the KGBJS equation by a small modification.

Forward jets in high energy factorisation at the lhc

We report on calculations of forward jet production at the Large Hadron Collider based on QCD high-energy factorization. In particular we emphasize dynamical features of the matrix elements controlling the resummation of logarithmically enhanced corrections in √s/E⊥, where E⊥ is the hardest jet transverse energy.
