| 英文摘要 | Introducing heavy particles with strong couplings to the Higgs field can strengthen electroweak phase transition through the entropy release mechanism from both bosons and fermions. We analyze the possibility of electroweak baryogenesis in the minimal supersymmetric Standard Model (MSSM) with new vectorlike superfields. The new vectorlike particles belong to the representation 5 + (5) over bar + 10 + (10) over bar of SU (5). By analyzing in detail the effective potential at finite temperature, we show that a strongly first-order electroweak phase transition in this model is ruled out by a combination of the 125 GeV Higgs requirement, the bound for exotic quarks, the gluon fusion Higgs production rate, and the Higgs diphoton decay rate, as well as the electroweak precision measurement. |
