通过W_L W_L散射识别更有效的无Higgsless理论
Identifying Better Effective Higgsless Theories via W_L W_L Scattering
摘要：
三位点Higgsless模型是研究Higgsless模型的对撞机现象学的一个基准。在这次演讲中，我们介绍了如何以及三个网站的Higgsless模型作为一个通用的代表Higgsless模型在描述W_L W_L散射，以及哪些修改可以使它更具有代表性。我们采用一般求和规则的质量和耦合的卡鲁扎-克莱因（KK）模式的规范场在连续和解构希格斯模型作为一种方式来比较不同的理论。在比较了三格点Higgsless模型与平坦和弯曲连续介质Higgsless模型的异同后，我们分析了三格点Higgsless模型的一种扩展，即HLS Higgsless模型。我们证明了HLS无Higgsless模型中的W_LW_L散射可以非常接近连续介质模型中的散射，只要选择参数“a”来模拟QCD中ρ介子主导的π-π散射.
英文摘要：
The three site Higgsless model has been offered as a benchmark for studying the collider phenomenology of Higgsless models. In this talk, we present how well the three site Higgsless model performs as a general representative of Higgsless models in describing W_L W_L scattering, and which modifications can make it more representative. We employ general sum rules relating the masses and couplings of the Kaluza-Klein (KK) modes of the gauge fields in continuum and deconstructed Higgsless models as a way to compare the different theories. After comparing the three site Higgsless model to flat and warped continuum Higgsless models, we analyze an extensions of the three site Higgsless model, namely, the Hidden Local Symmetry (HLS) Higgsless model. We demonstrate that W_LW_L scattering in the HLS Higgsless model can very closely approximate scattering in the continuum models, provided that the parameter `a' is chosen to mimic rho-meson dominance of pi-pi scattering in QCD.
