Unintegrated parton distributions and correlation functions

We discuss the limitations of the standard collinear approach. The kinematical approximations necessary to derive the collinear factorization are insufficient for the description of the exclusive final states. We argue that for a proper treatment of the final states one needs to use fully unintegrated parton correlation functions. We introduce the gauge invariant definitions of these objects and the factorization theorem for one jet production in deep inelastic scattering.Comment: 6 pages, 3 figures, pdflatex.

RHIC physics: short overview

This talk gives a very short overview of some of the important physical phenomena observed at the Relativistic Heavy Ion Collider (RHIC). The emphasis is put on the multiplicities, hard probes and the properties of the initial state.Comment: 8 pages, 5 figures, pdflatex.

Nonlinear evolution equations in QCD and effective Hamiltonian at high energy

In this talk I briefly present recent developments in the theory of the Color Glass Condensate. The duality between the dense and dilute regimes of the gluon field is discussed as well as the effective selfdual Hamiltonian which includes both Pomeron merging and Pomeron splitting.Comment: 4 pages.

Unintegrated Double Parton Distributions - a Summary

We present main elements of the construction of unintegrated double parton distribution functions which depend on transverse momenta of partons. We follow the method proposed by Kimber, Martin and Ryskin for a construction of unintegrated single parton distributions from the standard parton distribution functions.Comment: presented at "Diffraction 2016", International Workshop on Diffraction in High Energy Physics, Acireale (Catania, Sicily), Sept 2-8 2016, to be published in the conference proceedings by AI
