FYI (I got this while in Poland and could not forward from there -sorry for the delay). ------------------------------------------------------ Flemming Videbaek Physics Department Brookhaven National Laboratory tlf: 631-344-4106 fax 631-344-1334 e-mail: videbaek@bnl.gov Subject: Abstract of Phobos paper on dAu results | Dear Tom, | | Below is the title and abstract of the dAu paper which we plan to | submit to PRL. | | Consistent with our understanding of the plans for the press release, it is our | intention not to submit this paper in a week's time, but instead hold off until | Wednesday, June 18. In fact, we would like to propose that all the | papers related | to the press release be submitted at the same time to PRL, with a request | that they appear next to each other in the same issue. | | All the very best, | Wit | | Centrality dependence of charged hadron transverse momentum spectra | in d+Au collisions at sqrt(s_NN) = 200 GeV | | | We have measured transverse momentum distributions of charged hadrons | produced in d+Au collisions at sqrt(s_NN) = 200 GeV. | The spectra were obtained for transverse momenta 0.25 < p_T < 6.0 GeV/c, | in a pseudorapidity range of 0.2 < \eta < 1.4 in the hemisphere of the | outgoing deuteron fragments. The evolution of the spectra with collision | centrality is presented in comparison to p+pbar collisions at the same | collision energy. With increasing centrality, the yield at high transverse | momenta increases more rapidly than the overall particle density, | leading to a strong modification of the spectral shape. This change | in spectral shape is qualitatively different from observations in Au+Au | collisions at the same energy. The data provide important information | for discriminating between different models of the suppression of | high p_T hadrons observed in Au+Au collisions. | |
