Title:  Composite Higgs and Dark Matter

Abstract: 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.
