On the Top Quark's Chiral Weak-Moment

Abstract

For the observed t --> W b decay, an intensity-ratio equivalence-theorem for two Lorentz-invariant couplings is shown to be related to symmetries of tWb-transformations. Three explicit tWb-transformations, A_{+}=M A_{SM}, ... relate the four standard model's helicity amplitudes, A_{SM}, and the amplitudes A_{+} in the case of an additional t_R --> b_L weak-moment of relative strength Lambda_{+} =E_W /2 = 53 GeV. Two commutator plus anti-commutator symmetry algebras are generated from M, P, B. These transformations enable a simple and uniform characterization of the values of Lambda_{+}, m_W/m_t, and m_b/m_t.
