Recent Results from the BRAHMS Experiment | | P. Staszel
; | | Date: |
21 Oct 2005 | | Affiliation: | for the BRAHMS Collaboration | | Abstract: | We present recent results obtained by the BRAHMS experiment at the Relativistic Heavy Ion Collider (RHIC) for the systems of Au + Au and Cu + Cu at
ootsnn{200} and at 62.4 GeV, and p + p at
ootsnn{200}. Nuclear modification factors for Au + Au and Cu + Cu collisions are presented. Analysis of anti-particle to particle ratios as a function of rapidity and collision energy reveal that particle populations at the chemical freeze-out stage for heavy-ion reactions at and above SPS energies are controlled by the baryon chemical potential. From the particle spectra we deduce significant radial expansion ($eta approx $ 0.75), as expected for systems created with a large initial energy density. We also measure the elliptic flow parameter $v_2$ versus rapidity and ptn. We present rapidity dependent $p/pi$ ratios within $0 < y < 3$ for Au + Au and Cu + Cu at
ootsnn{200}. Raa is found to increase with decreasing collision energy, decreasing system size, and when going towards more peripheral collisions. However, Raa shows only a very weak dependence on rapidity (for $0 < y < 3.2$), both for pions and protons. | | Source: | arXiv, nucl-ex/0510061 | | Services: | Forum | Review | PDF | Favorites | |
