Indications for an anomalous right-handed coupling of the b-quark from a model independent analysis of LEP and SLD data on Z decays

A model independent analysis is made using the LEP and SLD data on Z decays available at the end of 1996. The effective weak coupling constants of leptons, c quarks and b quarks are extracted. Except for the right-handed b quark coupling, they all agree well with the predictions of the Standard Elec...

description A model independent analysis is made using the LEP and SLD data on Z decays available at the end of 1996. The effective weak coupling constants of leptons, c quarks and b quarks are extracted. Except for the right-handed b quark coupling, they all agree well with the predictions of the Standard Electroweak Model for $m_t = 172$ GeV and $m_H = 263$ GeV. The right-handed b quark coupling is found to be 42$\%$ and 3.2 standard deviations above the Standard Model prediction.
