在LHC上寻找奇异的希格斯玻色子

Searching exotic Higgs bosons at the LHC

Gautam Bhattacharyya, Siddharth Dwivedi, Dilip Kumar Ghosh, Gourab Saha, Subir Sarkar

摘要:

我们分析在一个独立的模式的方式挖掘出中性奇异希格斯态的可能性,如果他们存在赋予与普通物质和规范场的非常规耦合,在14 TeV运行的大型强子对撞机(LHC),增加了一些比较研究13.6和13 TeV的运行。味模型,基于一些离散的对称群,扩展标量扇区已知产生奇异的自旋0状态,CP-偶和CP-奇,与纯味非对角汤川耦合。这种CP偶态的规范相互作用也是不寻常的,不像标准模型的希格斯玻色子,它不耦合到规范玻色子对。这种非常规的性质使这些奇异态不受传统的对撞机和电弱约束,因此这些态可能是轻的。没有承诺任何特定的模型,利用其独特的汤川和规范属性,我们探索发现这些奇异的希格斯态的潜力,通过一些有趣的拓扑结构,找出一些特定的运动学变量,抑制背景。

英文摘要:

We analyse in a model independent way the possibilities of digging out neutral exotic Higgs states, should they exist endowed with unconventional couplings with ordinary matter and gauge fields, at the 14 TeV run of the Large Hadron Collider (LHC), adding some comparative studies for 13.6 and 13 TeV runs. Flavor models, based on some discrete symmetry groups, with extended scalar sectors are known to yield exotic spin-0 states, both CP-even and CP-odd, with purely flavor off-diagonal Yukawa couplings. The gauge interaction of one such CP-even state is also unusual that, unlike the Standard Model Higgs boson, it does not couple to gauge boson pairs. Such unconventional properties immune these exotic states from receiving traditional collider and electroweak constraints, and hence those states could be light. Without committing to any specific model, exploiting their peculiar Yukawa and gauge properties, we explore the discovery potential of those exotic Higgs states through some interesting topologies by figuring out some specific kinematic variables that suppress the backgrounds.
