摘要
具有普适费米子耦合的原始小希格斯模型被发现与电弱精确数据一致，但受到Tevatron对预言中的弱耦合Z'玻色子的限制的强烈约束。CDF在240 GeV处观测到的一个可能信号与预言的Z'一致，而低于150 GeV的区域在很大程度上不受对撞机数据的约束。

14 pages, 3 figures. Version 2 corrects coding error for Moller scattering and includes effect of Z-Z' mixing on Z' decays, with small changes in results. Added new figures, tables, and citations. Version 3 is as published in PRD, adds discussion of fine tuning of model parameters
