Abstract

Results are reported on a high statistics study of Bhabha scattering at 29 GeV in the polar angle region, |cos θ| < 0.55. The data are consistent with the standard model, and measure vector and axial-vector coupling constants of g_v² = 0.03 ± 0.09 and g_a² = 0.46±0.14. Limits on the QED-cutoff parameters are Λ₊ > 154 GeV and Λ_- > 220 GeV. Lower limits on scale parameters of composite models are in the range 0.9-2.8 TeV. The partial width of a hypothetical spin-zero boson decaying to e⁺e^- has an upper limit which varies from 6 to 57 MeV corresponding to a boson mass in the range 45-80 GeV/c².
