在ILC上亲轻子双Higgs模型中的多τ轻子特征

Multi-tau lepton signatures in leptophilic two Higgs doublet model at the ILC

Shinya Kanemura, Koji Tsumura, Hiroshi Yokoya

摘要:

本文研究了X型双希格斯粒子模型(THDM-X)在对撞机实验中的可行性。在THDM-X中,新的希格斯玻色子在参数空间的宽范围内大多衰变为τ轻子。由于夸克汤川相互作用的抑制,这种标量玻色子不受当前实验数据的限制。讨论了在国际直线对撞机和大型强子对撞机上对多τ轻子末态的THDM-X的搜索策略。利用共线近似,我们证明了4 τ轻子签名(e^+e^- -> HA -> 4τ)可以是一个干净的信号。

英文摘要:

We study the feasibility of the Type-X two Higgs doublet model (THDM-X) at collider experiments. In the THDM-X, new Higgs bosons mostly decay into tau leptons in the wide range of the parameter space. Such scalar bosons are less constrained by current experimental data, because of the suppressed quark Yukawa interactions. We discuss a search strategy of the THDM-X with multi-tau lepton final states at International linear collider and Large Hadron Collider. By using the collinear approximation, we show that a four tau lepton signature (e^+e^- -> HA -> 4τ) can be a clean signal.
