NEW RESULTS FROM BHABHA SCATTERING AT 29 GEV
- 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 gv2 = 0.03 ± 0.09 and ga2 = 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+...
