Abstract

We have observed K o s production in e + e − annihilation between 3.6 and 4.4 GeV CMS energy. In the 4.0–4.1 GeV range K o s mesons occur correlated with prompt electrons, indicating the formation and weak decay of charmed particle. Within the sensitivity of the experiment, no K o s -electron correlation is seen at 3.6 and around 4.4 GeV
