Precision Data and Implications on the Parameters of TC theory

Abstract

Assuming that the actual values of $m_t$ and the data set (${\Gamma }_b$, ${\Gamma }_h$, ${\Gamma }_Z$, $R_b$, $R_c$, $R_l$) are within their $1-\sigma$ errors as reported by CDF, D0 and by LEP Collaborations, the parameter ${\Delta }_b^{new}$ which measures the nonoblique corrections on the $Zb\overline{b}$ vertex from new physics can be determined experimentally. According to the precision data one can obtain updated constraints on the parameters $\xi$ and the masses of the charged PGBs.
