自下而上全息术中的无光子线性限制
Linear confinement without dilaton in bottom-up holography for walking technicolour
摘要：
在PRD 78（2008）055005 [arXiv：0805.1503 [hep-ph]]和PRD 79（2009）075004 [arXiv：0809.1324 [hep-ph]]中，我们使用硬壁和软壁模型构建了行走技术色理论的全息描述。在这里，我们表明，一旦一个术语被包括在拉格朗日混合的戈德斯通玻色子和轴向矢量介子的纵向分量的自旋共振谱的现象学上变得无关。我们展示了这种混合如何影响我们以前的结果，我们预测如何可以测试这种描述的technicolour。
英文摘要：
In PRD78(2008)055005 [arXiv:0805.1503 [hep-ph]] and PRD79(2009)075004 [arXiv:0809.1324 [hep-ph]], we constructed a holographic description of walking technicolour theories using both a hard- and a soft-wall model. Here, we show that the dilaton field becomes phenomenologically irrelevant for the spectrum of spin-one resonances once a term is included in the Lagrangian that mixes the Goldstone bosons and the longitudinal components of the axial vector mesons. We show how this mixing affects our previous results and we make predictions about how this description of technicolour can be tested.
