Description
Searches for low mass CP-odd Higgs boson (A0) predicted
in non-minimal supersymmetric extensions of the Standard Model,
and for dark-sector Higgs-like and gauge bosons motivated by
recent astrophysical observations, have been performed at Babar
studying the radiative decays of the Y(nS) resonances, with n=1,2,3,
and multiparticle production in e+e- annihilations.
Stringent limits on the production of a light Higgs boson and
on the SM-dark sector mixing parameter have been set.
