Abstract: (Elsevier)

A search for the production of charged scalars has been carried out in e + e − annihilation at center of mass energies up to 64 GeV with 61.1 pb −1 of integrated luminosity using the VENUS detector at TRISTAN. The assumptions concerning the production and decay of hypothetical charged scalars are minimal; they are expected to be singly charged and decay into a pair of fermions. No positive evidence for their production has been found in a study of all combinations of the ℓ ν(ℓ ν ) and U D ( U D ) decay channels. We have excluded the mass region of 8.0–20.0 GeV/ c 2 regardless of the decay mode.
