Abstract
We report the first measurement of inclusive antiproton production at midrapidity in collisions at by the STAR experiment at RHIC. The antiproton transverse mass distributions in the measured transverse momentum range of 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.
