Abstract

An experiment to search for the production of neutral penetrating particles decaying into electron-positron pairs was performed with a 2.5-GeV electron beam. A total of 0.027 C was injected into a tungsten target. No such particle is found. Constraints on coupling constants ${\ensuremath{\alpha}}_{e}$ and ${\ensuremath{\alpha}}_{\ensuremath{\gamma}}$ are given.
