Pair production of the doubly charged leptons X±± via vector boson fusion (γγ, Zγ and WW) at the large hadron collider is studied. Our numerical results show that the cross section via Zγ fusion is very small. For the center-of-mass energy √s= 14 TeV and Mx = 200 650 GeV, the values of the cross sections σγγ and σww are in the ranges of 5.2 fb-0.04 fb and 20.2 fb 1.2 fb, respectively. 相似文献

Type-III seesaw scenario predicts the existence of the heavy charged leptons, which might generate observable signals in future collider experiments. We consider the contributions of these new particles to the process e+e- →HH. We find that, for the large mixing between the light and heavy leptons, these new particles can indeed generate significant contributions to this process. 相似文献

Axion-like particles(ALPs)are often defined as relatively light pseudoscalar particles and appear in many extensions of the Standard Model.Taking into account constraints on the free parameters from existing searches and explaining the g-2 deviation,we consider the contributions of ALPs with mass in the range of 1.5GeVm_am_h-m_Z to the exclusive Higgs decays h→PZ and h→Pe~+e~-with P being the pseudoscalar mesonsπ~0,η,η',η_c andη_b in a model-independent approach.We find that,in most of the parameter space range,the contributions of ALP to these decay-processes are ver.y small,while in the case of the ALP mass ma approximatel.y equaling the meson mass m_P,the contributions are significantly large. 相似文献
