    • The charge retention form of the Lagrangian is obtained from the usual standard model charged current-current form through the Fierz transformation (B1) written down in Appendix B. The minus sign from the Fierz identity is cancelled from having to commute the Fermion fields an odd number of times in order to relate the two forms. Note that the Fierz identity is a four-dimensional identity. Since our calculations are done in four dimensions the Fierz identity can be safely applied.

    • In our numerical results for the longitudinal and transverse polarization of the daughter lepton and the forward-backward asymmetry we have not expanded out the inverse of the denominator function in terms of powers of α.
