Abstract: (APS)
We search for the decay Υ(1S)→γA0, A0→gg or ss¯, where A0 is the pseudoscalar light Higgs boson predicted by the next-to-minimal supersymmetric Standard Model. We use a sample of (17.6±0.3)×106 Υ(1S) mesons produced in the BABAR experiment via e+e-→Υ(2S)→π+π-Υ(1S). We see no significant signal and set 90%-confidence-level upper limits on the product branching fraction B(Υ(1S)→γA0)·B(A0→gg or ss¯) ranging from 10-6 to 10-2 for A0 masses in the range 0.5–9.0  GeV/c2.
