Abstract
We search for a low-mass scalar CP-odd Higgs boson, A[superscript 0], produced in the radiative decay of the upsilon resonance and decaying into a τ[superscript +]τ[superscript −] pair: Υ(1S) → γA[superscript 0]. The production of Υ(1S) mesons is tagged by Υ(2S) → π[superscript +]π[superscript −]Υ(1S) transitions, using a sample of (98.3 ± 0.9) × 10[superscript 6] Υ(2S) mesons collected by the BABAR detector. We find no evidence for a Higgs boson in the mass range 3.5 ≤ m[subscript A0] ≤ 9.2  GeV, and combine these results with our previous search for the tau decays of the light Higgs in radiative Υ(3S) decays, setting limits on the coupling of A[superscript 0] to the b[bar over b] quarks in the range 0.09–1.9. Our measurements improve the constraints on the parameters of the next-to-minimal-supersymmetric Standard Model and similar theories with low-mass scalar degrees of freedom.
