Precision Data and Implications on the Parameters of TC Theory

Assuming that the actual values of mt and the data set (Γ_b,Γ_h,Γ_Z, R_b,R_c,R_l) are within their 1-σ errors as reported by CDF, DO and by LEP Collaborations, the parameter Δ_b^new 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.
