摘要：

With the experimental data from STAR on the multiplicity dependence of the transverse momentum spectra of charged particles in pp collisions at root(NN)-N-S = 200 GeV, we investigate the scaling property of the spectra in those collisions. Using the scaling functions of pion and proton obtained in studying spectra in Au + Au and d + Au collisions, we describe the charged particle PT spectra in pp collisions as a superposition of those front pion and proton. Species contents are obtained and p/pi ratio is given as a function Of PT for events with some given charged multiplicities. (c) 2008 Elsevier B.V. All rights reserved.
