Higgs sectors with exotic scalar fields

Understand

The discovery of the Higgs boson like particle with the mass of around 126 GeV has given us a great clue to know what is the true Higgs sector.

• New physics models at the TeV scale often introduce Higgs sectors extended from the minimal form, so that the determination of the Higgs sector can be a probe of new physics models.
• In this talk, we focus on the Higgs sector with exotic representation fields whose isospin is larger than 1/2.
• We first discuss the general features of exotic Higgs sectors, and then we consider several concrete models to clarify them.
