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.
