The minimum-bias multiplicity distribution and the transverse momentum and pseudorapidity distributions for central collisions have been measured for negative hadrons ( h(-)) in Au+Au interactions at square root of ([s(NN)]) = 130 GeV. The multiplicity density at midrapidity for the 5% most central interactions is dN(h(-))/d(eta)/(eta = 0) = 280+/-1(stat)+/-20(syst), an increase per participant of 38% relative to pp collisions at the same energy. The mean transverse momentum is 0.508+/-0.012 GeV/c and is larger than in central Pb+Pb collisions at lower energies. The scaling of the h(-) yield per participant is a strong function of p( perpendicular). The pseudorapidity distribution is almost constant within /eta/<1.
在(\sqrt{[s(NN)]}=130)GeV的金金碰撞中，已测量了负强子（(h^-)）的最小偏差多重性分布以及中心碰撞的横向动量和赝快度分布。对于5%最中心的相互作用，中快度处的多重性密度为(dN(h^-)/d\eta|_{\eta = 0}=280\pm1)（统计）(\pm20)（系统），相对于相同能量下的质子质子碰撞，每个参与者的多重性增加了38%。平均横向动量为(0.508\pm0.012)GeV/c，且大于较低能量下中心铅铅碰撞中的横向动量。每个参与者的(h^-)产额的标度是垂直动量(p_T)的强函数。赝快度分布在(|\eta|\lt1)范围内几乎是恒定的。
