标题： Pair production of single and double charged scalar pairs and their lepton flavor violating signals in the littlest Higgs model at LHC

摘要： 在本工作中，研究了在最小希格斯模型框架下，LHC上带电和双重带电标量的产生及其轻子味违反的对撞机信号。 在最小希格斯模型允许的参数区域内，通过$pp \to \phi^{++}\phi^{-}$、$pp \to \phi^+\phi^-$和$pp \to \phi^{++}\phi^{--}$过程计算了最小希格斯模型中标量的产生率。 我们得出结论，带电和双重带电标量对可以在LHC上产生。 考虑到文献中发现的带电标量可能的轻子味违反衰变，进行了最终态分析。 该分析表明，根据模型参数，来自最小希格斯模型的单重和双重带电重标量引起的轻子数和轻子味违反可以被LHC观测到。 显示英文摘要

摘要： In this work productions of charged and doubly charged scalars and their lepton flavor violating collider signals in the framework of littlest Higgs model at LHC are studied. In the allowed parameter region of the littlest Higgs model, the production rates of the scalars of littlest Higgs model via $pp \to \phi^{++}\phi^{-}$, $pp \to \phi^+\phi^-$ and $pp \to \phi^{++}\phi^{--}$ processes are calculated. We obtained that charged and doubly charged scalar pairs can be produced at LHC . Considering the possible lepton flavor violating decays of charged scalars found in literature, final state analysis is done. This analysis show that depending on the model parameters, lepton number and lepton flavor violations resulting from single and double charged heavy scalars of the littlest Higgs model can be observed at LHC.
