The authors search for a new light non-Standard Model CP-odd Higgs boson, A{sup 0}, decaying to {tau}{sup +}{tau}{sup -}, {mu}{sup +}{mu}{sup -}, and invisible in radiative decays of the {Upsilon}(2S) and {Upsilon}(3S). We search for the light scalar particle produced in single-photon decays of the {Upsilon}(3S) resonance through the process {Upsilon}(3S) {yields} {gamma}A{sup 0}, A{sup 0} {yields} invisible. We also search for evidence of an undetectable {Upsilon}(1S) decay recoiling against the dipion system. The data samples contain 99 x 10{sup 6} {Upsilon}(2S) and 122 x 10{sup 6} {Upsilon}(3S) decays collected by the BABAR detector at the SLAC PEP-II B factory.
