The two most precise determinations of this quantity, based on the left-right asymmetry measured by SLD and the bb- forward-backward asymmetry measured at LEP, differ by s.

Both measurements are still statistics-dominated, but is this the first hint of new physics or just a fluctuation.

Recent measurements of the top quark forward-backward asymmetry at the Tevatron could hint at new physics with an unexpected flavor structure. The significance of such an abnormal flavor structure in alleviating the tension between the inclusive and exclusive determinations of |V ub | via right-handed charge currents is studied.

Another observable that can be measured experimentally is the forward-backward asymmetry of the top quark [].Generally in a fermion pair production process, a forward-backward asymmetric distribution originates from an interference of the vector and axial-vector production.

The couplings of the fermions to the Z boson are of great importance in establishing the validity of the Standard Model and in looking for physics beyond it. The LEP experiment at CERN provided accurate measurements of the Z neutral gauge boson properties.

Although all measurements agree well with the SM predictions, the forward–backward asymmetry of the bottom-quark remains almost 3 σ away from the SM value. We proposed that this anomaly may be explained by the existence of a new U (1) D gauge boson, which couples with Author: Da Liu, Jia Liu, Carlos E.
