Abstract

We have studied at CM energies of 14, 22 and 30-36.7 GeV e+e- annihilation events in which the hadronic final state contains both a proton and an antiproton in the momentum range 1.0 <p <GeV/c. We find that such pairs are produced predominantly in the same jet and conclude that baryon-antibaryon production is dominated by a mechanism involving local compensation of baryon number.
