Precision muon g-2 results and light Higgs bosons in the 2HDM(II)
  We discuss the implications of the recent evaluations of the SM contribution to a_mu=(g-2)_mu/2 in the light of the latest E821 measurement, which indicate \~ 3 sigma deviation. We derive the 95 % CL interval, delta a_mu, to be used to constrain any additional contribution to a_mu, beyond the SM ones; it has to have a positive sign. We apply the delta a_mu to constrain the light Higgs-boson scenarios in a Two-Higgs-Doublet-Model (``Model II''). If the constraints from the new (g-2)_mu 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 beta in the range 25 < tan beta < 115.
