Abstract

We present results from Experiment 864 for antiproton production and antideuteron limits in Au + Pb collisions at 11.5 [Formula Presented] per nucleon. We have measured invariant multiplicities for antiprotons for rapidities [Formula Presented] at low transverse momentum as a function of collision geometry. When compared with the results from Experiment 878 our measurements suggest a significant contribution to the measured antiproton yield from the decay of strange antibaryons. We have also searched for antideuterons and see no statistically significant signal. Thus, we set upper limits on the production at approximately [Formula Presented] per 10% highest multiplicity Au+Pb interaction.
