Abstract

We report the first measurement of inclusive antiproton production at midrapidity in Au+Au collisions at sNN=130GeV by the STAR experiment at RHIC. The antiproton transverse mass distributions in the measured transverse momentum range of 0.25<p<0.95GeV/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.
