Description
1. Color Glass Condensate and forward physics at the LHC
by François Gelis / CEA, Saclay
After a brief review of the physics of parton saturation and of the current state of the art in its description by the Color Glass Condensate, I'll focus on particle production at forward rapidities. In particular, I'll discuss phenomena such as limiting fragmentation, shadowing, and multiple scattering, which can all be used in order to test various aspects of the Color Glass Condensate framework.
2. Properties of matter at forward rapidities at RHIC
by Dieter Röhrich / Univ. of Bergen
The BRAHMS experiment at RHIC has measured pions, kaons and protons and their antiparticles over a wide range of rapidity and transverse momenta. Au+Au collisions, d+Au and p+p interactions have been studied. Pt-spectra in p+p interactions will be compared to NLO pQCD. The nuclear modification factor for d+Au collisions at \sqrt(s_NN)=200 GeV changes from a Cronin-like enhancement of pions (and charged hadrons) at midrapidity to an increasing suppression at forward rapidities. In central Au+Au collisions at 200 GeV a strong pion suppression is observed in R_{AuAu} at all rapidities, while protons are enhanced at all rapidities.
