The mechanism of Electro-Weak symmetry breaking is still not understood. LHC will probe the relevant energy range in a few years and will hopefully provide the necessary clues that will lead to a solution. Since no approach to explaining electroweak symmetry breaking is presently theoretically compelling and experimentally tested, it is worthwhile to explore any approach that might lead to progress in this area. The PI's propose to both explore alternative approaches in the sense of building models, and to work out constraints from collider and precision data. One aspect of this proposal is to explore an alternative to the Higgs mechanism as the origin of mass. The idea is to use Kaluza-Klein towers of massive vector bosons to delay the unitarity violations that occur without a Higgs mechanism. The PI?s plan to further study this model and its generalizations. Having an alternative scenario for generating mass other than a Higgs particle will be very important if the Higgs is not found at Tevatron or LHC energies.

电弱对称性破缺的机制至今仍不清楚。LHC将在几年内探测相关的能量范围，并有望提供必要的线索，从而找到解决方案。由于目前还没有一种解释电弱对称性破缺的方法在理论上令人信服，也没有经过实验检验，因此值得探索任何可能在这一领域取得进展的方法。PI建议在构建模型的意义上探索替代方法，并从对撞机和精度数据中确定约束条件。该提议的一个方面是探索希格斯机制作为质量起源的替代方案。这个想法是使用卡鲁扎-克莱因塔的大质量矢量玻色子，以延迟发生没有希格斯机制的幺正性违反。私家侦探？我们计划进一步研究这个模型及其推广。如果在Tevatron或LHC能量下没有发现希格斯粒子，那么有一种替代方案来产生希格斯粒子以外的质量将非常重要。
