The BRAHMS experiment has unique capabilities to measure particle
production over a wide range of rapidity. This paper presents the
latest results how the medium evolves from midrapidity to the
forward region in the ultra-relativistic collisions at RHIC. The
rapidity loss at RHIC energies is shown for nucleus+nucleus
system. The studies of proton enhancement to the pion yield at
intermediate pT are presented for p+p and Au+Au reactions.
For d+Au collisions at = 200 GeV pions, kaons and
protons are all suppressed at forward rapidity.
Key words:
forward rapidity, nuclear stopping, particle ratios, nuclear
modification factor
