Description
Search for baryon pairs production in e+e- annihilation at √s=2386 MeV is reported. The data relate to a luminosity of 161 nb-1 collected by the DM2 experiment at DCI, the Orsay colliding ring. First measurements of direct e+e- annihilation into Λanti Λ and of e+e-→panti p at this energy are presented. First observation of a good e+e-→nanti n candidate is reported and upper limits are given for e+e-→nanti n, Λanti Σ0+c.c. and Σ0anti Σ0. (orig.)
