Description

We discuss the implication of recent evaluation of the SM contribution to (g - 2)μ in light of the latest E821 measurement, for the light Higgs-boson scenarios in a Two-Higgs-Doublet-Model (''Model II''). If the constraints from the new (g - 2)μ results are combined with the other existing constraints, one can exclude a light-scalar scenario at 95% CL while a light-pseudoscalar scenario can be realized, for a pseudoscalar mass between 25 and 70 GeV with tan β in the range 25 ≤ tanβ ≤ 115.
