This Letter reports results of a search for radiative production, by e+e− annihilation of particles that interact only weakly in matter. The search has been made in the total data set of 115 pb−1 acquired with the ASP detector at the SLAC storage ring PEP (s=29 GeV). No anomalous signal was observed. The number of generations of light neutrinos has been limited to Nν<7.5 (90% confidence level). Limits are also placed on the masses of particles predicted to exist by models of supersymmetry.

The weak coupling constants of the electron, gVe and gAe, are determined from measurements of the total and differential cross sections for the reaction νμe→νμe. The data also place limits of interest on the magnitudes of a neutrino charge radius and a possible neutrino magnetic dipole moment.
Neutrino beam 0 - 5 GeV.
