Abstract: | Assuming that the actual values of mt and the data set (Γb,Γh,ΓZ, Rb,Rc,Rl) are within their 1-σ errors as reported by CDF, DO and by LEP Collaborations, the parameter Δbnew which measures the nonoblique corrections on the Zbb vertex from new physics can be determined experimentally. According to the precision data one can obtain updated constraints on the parameters ξ and the masses of the charged PGBs. |
