Description
Search for baryon pair 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 measurement of direct e+e- annihilation into ΛantiΛ and of e+e- → pantip at this energy are presented. First observation of a good e+e- → nantin, candidate is reported and upper limits are given for e+e- → nantin, ΛantiΣ0 + c.c. and Σ0antiΣ0
