Abstract

Heavy neutral spinless particles are searched for using e⁺e^- collision data of CM energies between 54 and 64 GeV, collected with the VENUS detector at TRISTAN. The existence of such a particle might explain the anomalous e⁺e^- → l⁺l^-γγ reaction recently reported by a LEP experiment. Negative results lead to constraints on the partial decay width of such particles to electrons: in narrow resonance cases, Γ_ee < 1MeV from Bhabha scattering data and Γ_eeΓB_γγ < 3 keV from γγ production data at the 95% CL for masses around 59 GeV/c².
