Abstract: We search for a new light non-Standard Model CP-odd Higgs boson, $A^0$, decaying to $τ^+τ^-$, $μ^+μ^-$, and invisible in radiative decays of the $Υ(2S)$ and $Υ(3S)$. We search for the light scalar particle produced in single-photon decays of the $Υ(3S)$ resonance through the process $Υ(3S) \to γA^0, A^0 \to$ invisible. We also search for evidence of an undetectable $Υ(1S)$ decay recoiling against the dipion system. The data samples contain $99 \times 10^6 Υ(2S)$ and $122 \times 10^6 Υ(3S)$ decays collected by the \babar\ detector at the SLAC PEP-II $B$ factory.
