QCD challenges in pp, pA and AA collisions at high energies

Aula Renzo Leonardi - Villa Tambosi

Str. delle Tabarelle, 286, 38123 Villazzano TN

This workshop addresses the discussion of QCD processes for which data have recently become available at the ongoing RHIC and LHC programmes, or are expected in the near future. Whereas inclusive processes with a hard scale can be calculated within pQCD in LO and NLO, calculations of exclusive processes are relatively new. They are presently being developed by formulating effective models consistent with QCD, such as for example for the spin structure of the pomeron. The linear description of QCD dynamics based on DGLAP and BFKL evolution equation can be tested by particle production data in $pp$, $pA$ and $AA$ collisions. At low values of Bjorken-$x$, the transition to a nonlinear behaviour of QCD dynamics as expressed in gluon saturation effects is expected. Moreover, particle production in $pA$ and $AA$ collisions is modified by shadowing effects and propagation in the medium, and a unified approach to incorporate these effects remains a challenge.
