In the minimal anomaly mediated supersymmetry breaking (AMSB) model, a universal contribution m0 to all the scalar masses is introduced in order to avoid the negative slepton mass problem. The Higgs spectrum and couplings are determined by four parameters: maux, m0, tan β and sign(μ). The sign of μ affects mA at large tan β and mh at small tan β. The CP-odd Higgs mass mA is usually much larger than mz and the lightest CP-even Higgs is simply analogous to the one in the standard model. The reach of the current and future Higgs searches in LEP, Tevatron and LHC for the AMSB parameter spaces in studied in detail.
