Abstract
This paper reports results of a search for production by radiative annihilation of particles that interact only weakly in matter. The search has been made in a data set corresponding to 110 acquired with the ASP detector at the Stanford Linear Accelerator Center storage ring PEP (√s =29 GeV). No anomalous signal has been observed, which limits the number of generations of light neutrinos to be <7.9 (at 90% C.L.). Limits are also placed on the masses of particles predicted to exist by models of supersymmetry.
