Description
We present an up-to-date analysis of the constraints the precision data impose on the (CP-conserving) two Higgs doublet model of type II with emphasis on the possible existence of very light neutral (pseudo)scalar Higgs boson with mass below 20-30 GeV. We show that even in the presence of such light particles, the 2HDM(II) can describe the electroweak data with the precision comparable to that given by the SM. Particularly interesting lower limits on the mass of the lighter neutral CP-even scalar h0 are obtained in the scenario with light CP-odd Higgs boson A0 and large tan β. (orig.)
