What many Higgses can do for you?


  报告题目: What many Higgses can do for you?

  The Brout-Englert-Higgs mechanism proposed half a century ago was finally confirmed experimentally at the LHC in 2012. A scalar particle was found at 125 GeV, and after 6 years of exploration, all of its measured properties are compatible with the Standard Model predictions for the minimal Higgs boson. Yet, it is well possible that the observed .Higgs is just the first member of a much richer Higgs sector. Investigation of non-minimal Higgs sectors remains a very active direction in particle phenomenology. In this talk I will give an overview of this field, focusing on the ideas rather than technical details. I will outline different options which are being considered and highlight specific signatures characteristic to each of them, both in terms of model building and collider and astroparticle phenomenology
