摘要：

We report the first measurement of inclusive antiproton production at midrapidity in Au + Au collisions at roots(NN) = 130 GeV by the STAR experiment at RHIC. The antiproton transverse mass distributions in the measured transverse momentum range of 0.25 < p(<perpendicular to>) < 0.95 GeV/c are found to fall less steeply for more central collisions. The extrapolated antiproton rapidity density is found to scale approximately with the negative hadron multiplicity density.
