A light non-standard Higgs boson: to be or not to be at a (Super) B factory?

Abstract

A light non-standard Higgs boson decaying mainly into ${\tau }^{+}{\tau }^{-}$ has not been yet ruled out by LEP searches in several scenarios. We verify that, in the context of the Next-to-Minimal-Supersymmetric Standard Model, a low-mass CP-odd (mostly but not completely singlet-like) Higgs boson can couple strongly enough to down-type fermions to be detected in radiative ${\rm Y}$ decays into tauonic pairs at a high-luminosity B factory. Possible spectroscopic effects of a mixing with ${\eta }_b$ resonances are also analyzed
