    Abstract

    The BRAHMS probes the hot and dense nuclear matter at the RHIC which has reached its design energy of √NN = 200 GeV for Au + Au collisions. The BRAHMS uses magnetic spectrometers for hadrons covering a large phase space 0 < y < 4 with good particle identification and momentum resolution. A comprehensive investigation of multiplicity distributions of emitted charged particles is carried out. Ratios of yields of antiparticles to particles are also measured as a function of rapidity. Rapidity dependent net-proton yield indicates that substantial transparency has been achieved in these collisions. Transverse momentum spectra of charged hadrons are measured up to 5 GeV/c which indicates a significant medium effect when compared to nucleon + nuclon reference spectra.
