Tevatron上的色共振：现象学和多喷流的发现潜力
Colored Resonances at the Tevatron: Phenomenology and Discovery Potential in Multijets
摘要：
除了标准模型之外，还有几类理论包含大量自旋为1的色八重态，一般称为“色子”。事实上，我们认为，色子不可避免地出现在光谱中时，新的有色粒子感到额外的限制力。色子在强子对撞机中是独特的，因为这是它们可以共振产生的唯一环境。在最简单的模型中，我们表明，色子自然衰减到多射流通过二次共振，这可以与所有现有的界限，即使是色子轻几百GeV。我们进行了代表性的案例研究，并表明，在Tevatron的四喷通道搜索具有很强的信号意义，而LHC面临着艰巨的挑战，这样的搜索。
英文摘要：
There exist several classes of theories beyond the Standard Model which contain massive spin-1 color octets, generically called "colorons". Indeed we argue that colorons inevitably appear in the spectrum whenever new colored particles feel an additional confining force. Colorons are distinctive at hadron colliders as this is the only environment in which they can be resonantly produced. In the simplest models we show that the coloron naturally decays to multijets via secondary resonances, which can be consistent with all existing bounds, even for colorons as light as a few hundred GeV. We perform representative case studies and show that a search in the four-jet channel at the Tevatron has strong signal significance, while the LHC faces formidable challenges for such a search.
