Abstract

Directed flow of antiprotons is studied in Au + Au collisions at a beam momentum of 11.5A GeV/c. It is shown that antiproton directed flow is anti-correlated to proton flow. The measured transverse momentum dependence of the antiproton flow is compared with predictions of the RQMD event generator. (C) 2000 Elsevier Science B.V.
