Searching for a light Higgs boson via the Yukawa process at lepton colliders
Eung Jin Chun, Tanmoy Mondal
Abstract
We explore the prospect of Yukawa production of a light boson which can exist in an extended Higgs sector. A particularly interesting case is the light pseudoscalar in Type-X two Higgs doublet model which can explain the anomalous magnetic moment of muon at large tanβ. Considering ILC Higgs factory with s=250 GeV, we show that the available parameter space can be fully examined by the (tau) Yukawa process at 5σ. We also demonstrate the mass reconstruction of such a light particle which helps to sizably minimize the background events.
