We report on inclusive production of Jψ (3.1)-mesons observed in e+e−-annihilation in the energy range s = 4.0–5.0 GeV. After substraction of the radiative tail of the ψ(3.7) direct production of the Jψ (3.1) is found to be in the order of 0.1

We have measured the production cross section for K s 0 in e + e − annihilation from 3.6 to 5.0 GeV center of mass energy. A substantial increase of the K s 0 yield is observed around 4 GeV in qualitative agreement with the charm hypothesis.
