摘要

通过将标准规范群扩展为 SU(3)c×SU(2)L×U(1)Y×U(1)XSU(3)_c \times SU(2)_L \times U(1)_Y \times U(1)_X,其中 XX 电荷仅由第三族携带,我们容纳了 LEP 对 RbR_b 的测量,并预测在 e+ee^+e^- 散射中 AFBbA_{FB}^{b} 可能出现可测量的偏差,以及 D0Dˉ0D^0 \bar D^0 混合可能接近其实验极限。本模型的独特之处在于 Z' 耦合具有世代依赖性,从而显式违反 GIM 机制,但仍可自然符合弱电束制约束。直接探测该 Z' 可能但具有挑战性。

Sections in italics, and the Figures, explain how this same model-building strategy (with different details) can accommodate different data on $R_b$ and $A^b$
