Produced Hadron Spectra in p + p Collisions at $\sqrt{s}$=200 GeV
ORAL
Abstract
The rapidity dependence of particle production in high energy p + p collisions can provide important information of parton distribution functions and the transport of baryon number. In addition, p + p collisions provide an elementary reference for heavy ion collisions. Identified charged hadron spectra resulting from p + p collisions at RHIC have been measured over a wide range of rapidity with BRAHMS for $\sqrt{s}$=200 GeV. We will present the spectra of positive and negative $\pi$ and p. The spectra are analyzed to extract rapidity densities over the rapidity range from 0 to near 4 which we compare to rapidity distributions of the same species of produced hadrons in Au + Au collisions at the same energy. The proton rapidity densities are used to determine nuclear stopping while the pion yields constrain the total entropy production.
