Description
Mixing of a non-standard pseudoscalar light Higgs boson with eta_b states could
both distort the bottomonium spectrum, sizeably altering the hyperfine
splittings M[Y(nS)]-M[eta_b(nS)], and induce the decay of eta_b states into
taus, also breaking lepton universality in Upsilon decays. Present experimental
constraints from BaBar, CLEO, CDF and LEP will be reviewed in the talk, showing
the corresponding exclusion limits for non-minimal supersymmetric extensions of
the Standard Model. We will finally consider perspectives of searching for
light Higgs-like particles at (Super) B factories and the LHC.
