I just received the following notice from Wit Busza on a muliplicity paper. As of this moment it is not available on the Phobos local pages. ------------------------------------------------------ Flemming Videbaek Physics Department Brookhaven National Laboratory tlf: 631-344-4106 fax 631-344-1334 e-mail: videbaek@bnl.gov Subject: new paper from Phobos > Dear Colleagues: > > The Phobos collaboration has completed its internal review of a paper on > pseudorapidity distributions. We plan to submit it to PRL in a week's time. > > In accordance with our agreement here is the title and abstract of the paper. > > > The charged-particle pseudorapidity density $dN_{ch}/d\eta$ has been > measured for Au+Au collisions at $\sqrt{s_{NN}}$=130 GeV at RHIC, using the > PHOBOS apparatus. The total number of charged particles produced for the > 3\% most central Au+Au collisions for $|\eta|\leq$5.4 is found to be > 4200$\pm$400. The evolution of $dN_{ch}/d\eta$ with centrality is > discussed, and compared to model calculations and to data from > proton-induced collisions. The data show an enhancement in charged-particle > production at mid-rapidity, while in the fragmentation regions, the results > are consistent with expectations from $pp$ and $pA$ scattering. > > > The data and analysis are substantially the same as that presented by Alan > Wuosmaa and Gunther Roland at QM2001 and therefore we were not planning to > have a seminar at BNL on these results. > > Best regards, > Wit > >
