We search for the decay Υ(1S)→γA[superscript 0], A[superscript 0]→gg or ss̅ , where A[superscript 0] is the pseudoscalar light Higgs boson predicted by the next-to-minimal supersymmetric Standard Model. We use a sample of (17.6±0.3)×10[superscript 6] Υ(1S) mesons produced in the BABAR experiment via e[superscript +]e[superscript -]→Υ(2S)→π[superscript +]π[superscript -]Υ(1S). We see no significant signal and set 90%-confidence-level upper limits on the product branching fraction B(Υ(1S)→γA[superscript 0])·B(A[superscript 0]→gg or ss̅) ranging from 10[superscript -6] to 10[superscript -2] for A[superscript 0] masses in the range 0.5–9.0 GeV/c[superscript 2].
