论文摘要
Mirror Twin Higgs（MTH）型号始终包含重型玻色子和额外的希格斯。此外，为了通过Seesaw机制容纳微小的中微子肿块，也可以在MTH扩展模型中引入新的重中微子。这种新的粒子和互动可能会导致对违反Lepton风味（LFV）过程的新贡献，包括$ \ ell_i \ to \ell_jγ$和$ \ ell_i \ to \ ell_j \ ell_j \ ell_k \ ell_l $。我们发现当前的实验数据可以严格限制参数空间，并且可能由下一代围墙测试某些LFV过程。新颗粒对哑光异常磁势量的一环贡献也计算出来。这种贡献仍然无法解决实验与标准模型的预测之间的差异。
Mirror Twin Higgs(MTH) models always contain heavy gauge bosons and extra Higgses. Besides, to accommodate tiny neutrino masses via seesaw mechanism, new heavy neutrinos can also be introduced in MTH extension models. Such new particles and interactions may lead to new contributions to the lepton flavor violating (LFV) processes, including $\ell_i \to \ell_jγ$ and $\ell_i \to \ell_j\ell_k\ell_l$. We find that current experimental data can stringently constrain the parameter spaces and certain LFV processes can possibly be tested by the next generation colliders. One-loop contributions of the new particles to the muon anomalous magnetic momentumare also calculated. Such contributions can still not solve the discrepancy between the experiments and the prediction of the standard model.
