Abstract

We consider a Z₂-symmetric Two Higgs Doublet Model (2HDM), where the vacuum expectation values of both doublets are non-vanishing. Unitarity constraints for the SM-like 2HDM are analyzed for the mass of the lightest Higgs boson in the range [115,127] GeV. New stringent bounds on tanβ, 0.17
