This paper addresses the question of the observability of neutral Higgs bosons through the leptonic decay in a two Higgs doublet model (2HDM). Both scalar and pseudo-scalar Higgs bosons (H, A) are considered. The model is set to type IV to enhance the leptonic decay. In such a scenario, a signal production process like or
would provide a clear signal on top of the background in a di-muon invariant mass distribution far from the Z boson pole mass. The analysis is based on a
-id algorithm which preselects events if they have two
jets by requiring a hadronic
decay. Several benchmark points are defined for the search, requiring a linear collider operating at
and 1 TeV. It is shown that the signal can be observed on top of the background in all benchmark points at an integrated luminosity of 1000
