ORIGINS Guest Prof. Pyungwon Ko: Dark matter model buildings along the Standard Model construction and phenomenology therein

The Standard Model (SM) for particle physics is surprisingly successful. I will first recapitulate basic assumptions and key aspects of the SM, emphasizing differences between global vs. local gauge symmetries. Then I will apply similar assumptions and aspects to the Dark Matter (DM) model buildings. I will discuss a few exemplary DM models and demonstrate theoretical/phenomenological importances of my approach, in particular, unitarity and theoretical consistency in the context of inelastic DM, galactic center gamma-ray excess, DM searches at colliders, and decaying heavy DM for AMS02, IceCUBE and the recent KM3.
