Query: Measurement of inclusive antiprotons from Au+Au collisions at 130 GeV   We report the first measurement of inclusive antiproton production at
mid-rapidity in Au+Au collisions at 130 GeV by the STAR experiment at RHIC. The
antiproton transverse mass distributions in the measured transverse momentum
range of 0.25 < pT < 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.
