标题： KK Higgs produced in association with a top quark pair in the bulk RS Model

摘要： 我们提出了一种在具有变形度规的Randall-Sundrum(RS)模型框架下寻找希格斯玻色子的第一个Kaluza-Klein(KK)模式的搜索策略。我们研究了这种大质量激发态与ttbar对在大型强子对撞机(LHC)上的产生。KK希格斯主要衰变为一个增强的ttbar最终状态，然后我们得到一个有趣的四顶点最终状态，其中两个是增强的。最终状态中的增强产物提高了在此通道中搜索KK希格斯的灵敏度，该通道的产生截面原本相当小。我们的结果表明，在LHC最高计划亮度下，KK希格斯共振的质量可达约1.2 TeV。超过这个质量，KK希格斯的截面太小，无法在LHC上探索，可能只有在未来的高能对撞机上才有可能。 显示英文摘要

摘要： We present a search strategy for the first Kaluza-Klein (KK) mode of the Higgs boson in the framework of the Randall-Sundrum (RS) model with a deformed metric. We study the production of this massive excitation in association with a ttbar pair at the Large Hadron Collider (LHC). The KK Higgs primarily decays into a boosted ttbar final state and we then end up with an interesting four-top final state of which two are boosted. The boosted products in the final state improve the sensitivity for the search of the KK Higgs in this channel whose production cross-section is otherwise rather small. Our results suggest that masses of the KK Higgs resonance upto about 1.2 TeV may be explorable at the highest planned luminosities of the LHC. Beyond this mass, the KK Higgs cross-section is too tiny for it to be explored at the LHC and may be possible only at a future higher energy collider.
