| 英文摘要 | The exo-Higgs model can accommodate a successful baryogenesis mechanism that closely mirrors electroweak baryogenesis in the Standard Model, but avoids its shortcomings. We extend the exo-Higgs model by the addition of a singlet complex scalar chi In our model,chi can be a viable asymmetric dark matter (ADM) candidate. We predict the mass of the ADM particle to be m(chi)approximate to 1.3GeV. The leptophilic couplings of chi can provide for efficient annihilation of the ADM pairs. We also discuss the LHC signals of our scenario, and in particular the production and decays of exo-leptons which would lead to "lepton pair plus missing energy" final states. Our model typically predicts potentially detectable gravitational waves originating from the assumed strong first order phase transition at a temperature of similar to TeV. If the model is further extended to include new heavy vector-like fermions, e.g. from an ultraviolet extension, chi couplings could explain the similar to 3.5smuon g-2anomaly. (C) 2017 The Authors.
