顶部三角形驼鹿:结合Higsless和Topcolor机制产生质量
The Top Triangle Moose: Combining Higgsless and Topcolor Mechanisms for Mass Generation
摘要:
我们提出了一个解构模型,结合了希格斯粒子和顶色机制的细节。该模型解释了在许多无希格斯玻色子模型中存在的获得正确顶夸克质量和保持Δ ρ小之间的紧张关系。它通过挑出顶夸克质量产生所产生的汤川耦合到一个有效的顶希格斯,开发一个小的真空期望值,而电弱对称性破缺的结果主要来自一个希格斯机制。因此,标准模型费米子的重伙伴可以轻到足以在大型强子对撞机上看到。在介绍了模型之后,我们详细描述了现象学,表明在广泛的质量范围内,这些重费米子在LHC中是可分离的。
英文摘要:
We present the details of a deconstructed model that incorporates both Higgsless and top-color mechanisms. The model alleviates the tension between obtaining the correct top quark mass and keeping Delta rho small that exists in many Higgsless models. It does so by singling out the top quark mass generation as arising from a Yukawa coupling to an effective top-Higgs which develops a small vacuum expectation value, while electroweak symmetry breaking results largely from a Higgsless mechanism. As a result, the heavy partners of the standard model fermions can be light enough to be seen at the LHC. After presenting the model, we detail the phenomenology, showing that for a broad range of masses, these heavy fermions are discoverable at the LHC.
