Forward Production With Large p/πRatio and Without Jet Structure at Any p_T
arXiv:nucl-th/0605037 · doi:10.1103/PhysRevC.76.014901
Abstract
Particle production in the forward region of heavy-ion collisions is shown to be due to parton recombination without shower partons. The regeneration of soft partons due to momentum degradation through the nuclear medium is considered. The degree of degradation is determined by fitting the ratio. The data at GeV and from BRAHMS on the distribution of average charged particles are well reproduced. Large proton-to-pion ratio is predicted. The particles produced at any should have no associated particles above background to manifest any jet structure.
