Technicolor的统一性

Unitarity in Technicolor

Roshan Foadi, Matti Järvinen, Francesco Sannino

摘要:

研究了具有自旋单轴矢量态和复合Higgs粒子的动态电弱对称性破缺模型中的纵向$WW$散射。我们还研究了复合自旋二态的效应,它具有与大质量引力子相同的性质。任何动力学电弱对称性破缺的模型,都会根据动力学的不同,将这些基本共振的一部分或全部作为低能谱的一部分。我们建议如何采取限制在有效的拉格朗日参数空间再现不同类型的基本规范理论的动力学,从传统的Technicolor模型,以最新的具有近共形动力学。我们研究了光复合希格斯粒子对纵向$WW$散射的直接影响以及光轴共振对纵向散射的间接影响。

英文摘要:

We investigate the longitudinal $WW$ scattering in models of dynamical electroweak symmetry breaking featuring a spin one axial and vector state and a composite Higgs. We also investigate the effects of a composite spin two state which has the same properties of a massive graviton. Any model of dynamical electroweak symmetry breaking will feature, depending on the dynamics, some or all these basic resonances as part of the low energy spectrum. We suggest how to take limits in the effective Lagrangian parameter space to reproduce the dynamics of different types of underlying gauge theories, from the traditional Technicolor models to the newest ones featuring nearly conformal dynamics. We study the direct effects of a light composite Higgs and the indirect ones stemming from the presence of a light axial resonance on the longitudinal $WW$ scattering.
