The rapidity dependence of the proton-to-pion ratio in Au+Au and p+p collisions at sqrt(sNN) = 62.4 and 200 GeV | P. Staszel

28 Jul 2009 | Abstract: | The BRAHMS measured proton-to-pion ratios in Au+Au and p+p collisions at
ootsnn{62.4} and
ootsnn{200} are presented as a function of transverse
momentum and collision centrality within the pseudo-rapidity range 0 < eta <
3.8 The results for Au+Au at sqrt(sNN) = 200 GeV are compared with predictions
from models which incorporate hydro-dynamics, hadron rescattering and jet
production, in the eta interval covered. In Au+Au collisions at sqrt(sNN) = 200
GeV, eta ~ 2.2, and at sqrt(sNN) = 62.4 GeV, eta = 0, the bulk medium can be
characterized by the common value of mi_B ~ 65 MeV. The p/pi ratios measured
for these two selections display a striking agreement in the pT range covered
(up to 2.2 GeV/c). At collision energy of 62.4 GeV and forward pseudo-rapidity
we found a crossing point of p/pi+ ratios measured in central and
semi-peripheral Au+Au and in p+p reactions. The crossing occurs in the narrow
eta bin around value of 3.2, simultaneously in the whole covered pT range (0.3
GeV/c < pT < 2 GeV/c). | Source: | arXiv, 0907.4784 | Services: | Forum | Review | PDF | Favorites |
