ee对撞机中最小higgs模型的双电荷标量

Double charged scalars of littlest higgs model in ee colliders

Ayse Cagil

摘要:

由于SM的扩展对称群,小Higgs模型的粒子内容中含有重标量。在小Higgs模型中的最小Higgs模型中,存在着一个新的重标量三重态,它的物理态包括一个双电荷标量,一个单电荷标量,以及一个中性标量和一个中性赝标量。在小希格斯模型中,马约拉纳型质量项也可以在汤川拉格朗日中实现,导致轻子味破坏。本文介绍了在$e^+e^-$对撞机中,在最小Higgs模型的背景下,双电荷标量的对产生。此外,双电荷标量的最终签名将根据轻子味破坏参数进行分析。最后指出,在$e^+e^-$对撞机中,如果存在轻子味破坏,则在没有SM背景的情况下,可以用四轻子的对撞机信号观测到双荷标量;如果不存在轻子味破坏,则可以用背景分析重构双荷标量。

英文摘要:

Little Higgs models contain heavy scalars in their content of particles as a result of extended symmetry group of SM. In the littlest Higgs model of little Higgs models there exists a new heavy scalar triplet.The physical states of this triplet contains a double charged scalar, a single charged scalar, as well as a neutral scalar and a neutral pseudo scalar. In little Higgs models a Majorana type mass term can also be implemented in Yukawa Lagrangian, resulting lepton flavor violation. In this talk the pair productions of double charged scalars in the context of littlest Higgs model in $e^+e^-$ colliders are presented. Also the final signatures of double charged scalars will be analyzed depending on lepton flavor violation parameters. Finally it will be presented that if there is lepton flavor violation, double charged scalars can be observed without any SM background in $e^+e^-$ colliders with a collider signal of four leptons, otherwise if there is no lepton flavor violation they can be reconstructed with a background analysis.
