Charged Higgs Boson: Tracer of the Physics beyond Standard Model

Abstract

Charged Higgs boson can exist in many physics beyond the standard models (BSM) and it is the obvious BSM signal. We briefly describe why the 125GeV scalar discovered at the LHC must have (heavy) companion: the charged Higgs boson, in a new paradigm. We then focus on the charged Higgs phenomenology, especially on how to measure $\tan \beta$ precisely utilizing the top quark polarization information.
