| Abstract: | Measurements of e+e? → e+e? at 2.8 GeV are reported and interpreted in terms of limits for the mass and coupling of a possible scalar boson of the type introduced in recent renormalizable models of weak interactions. In particular, in the Georgi-Glashow scheme of leptons we find that the scalar boson mass must be larger than 10 GeV for an mW = 10 GeV (mW mass of the W-boson) and of 6.5 GeV for mW = 15 GeV. Alternatively its coupling is extremely weak. |
