Abstract

The inclusive production of antiprotons and Λ's in e+e- annihilation has been measured as a function of the c.m. energy in the range 3.7-7.6 GeV. We find that the baryon cross section has a behavior different from the total hadronic production. Our results show a rapid rise in the ratio σp̄σμμ between 4.4 and 5 GeV, consistent with what would be expected from charmed baryon production. Λ̄ production is 10-15% of p̄ production at all energies.
