new phobos paper on spectraFYI ------------------------------------------------------ Flemming Videbaek Physics Department Brookhaven National Laboratory Subject: new phobos paper on spectra Dear Tom, In a week's time the Phobos collaboration is planning to submit the following paper to Physics letters: Title: "Charged hadron transverse momentum distributions in Au+Au collisions at sqrt(s_NN) = 200 GeV" Abstract: "We present transverse momentum distributions of charged hadrons produced in Au+Au collisions at sqrt(s_NN) = 200 GeV. The spectra were measured for transverse momenta p_T from 0.25 to 4.5 GeV/c in a rapidity range of 0.2 < y_pi < 1.4. The evolution of the spectra is studied as a function of collision centrality, from 65 to 344 participating nucleons. The results are compared to data from proton-antiproton collisions and Au+Au collisions at lower RHIC energies. We find a significant change of the spectral shape between proton-antiproton and peripheral Au+Au collisions. Comparing peripheral to central Au+Au collisions, we find that the yields at high p_T exhibit approximate scaling with the number of participating nucleons, rather than scaling with the number of binary collisions." The results in this paper are essentially the same as those presented by Christof Roland at QM2002. All the best, Wit
