报告摘要：Although the standard model of particle physics has achieved great success in explaining most of the experimental results, it still has some problems. For example, it can not explain dark matter, the tiny mass of neutrinos, and the matter-antimatter asymmetry in the universe, etc. The Large Hadron Collider (LHC) discovered a 125 GeV Haggs particle in 2012, but whether it is a basic scalar particle or a composite particle remains an unsolved mystery. In this talk, I will introduce a theoretical scenario in which the Higgs is composite as a pseudo-Goldstone boson, and possible connections between this scenario and the dark matter.
