论文摘要
我们考虑对颜色三重速度费米子的实验限制，这些限制通过标量介质可以在可能的壳上或外壳中显着腐烂到三个喷气机。这些费用出现在可以解决层次结构问题的顶级模型中，并且这种情况的限制比传统顶级模型上的限制较弱，因为具有重要背景的全部最终状态。但是，我们确实发现，尽管没有针对此情况的专门搜索，尤其是在壳中调解人的情况下，LHC All-Hadronic搜索的套件仍然限制了参数空间的很大一部分。特别是，我们发现搜索DI-JET和Tri-JET共振的配对产生是互补的，涵盖了参数空间的不同区域。我们还发现，如果最终状态富含B-JET，那么当前的限制与所有光线喷头的方案相对于场景不会发生显着变化，我们描述了当前搜索策略的修改如何改善这种情况下的限制。
We consider experimental limits on colour triplet fermions that decay dominantly to three jets via a scalar mediator that can be on- or off-shell. These fermions arise in top-partner models that can solve the hierarchy problem, and limits on this scenario are weaker than those on traditional top-partner models because of the messy all-hadronic final state with significant backgrounds. We do find, however, that while there are no dedicated searches for this scenario, especially in case of an on-shell mediator, the suite of LHC all-hadronic searches still constrains a significant portion of the parameter space. In particular, we find that searches for pair production of di-jet and tri-jet resonances are complementary, covering different regions of parameter space. We also find that if the final state is rich in b-jets, current limits do not change significantly relative to the scenario with all light jets, and we describe how modifications of current search strategies can improve limits in that case.
