“…The candidates with A 0 masses between 2 and 4 GeV/c 2 are mostly Υ (1S) → γgg. CLEO measured the Υ (1S) → γf 2 (1270) [20] and Υ (1S) → γf ′ 2 (1525) [21] branching fractions. We do not expect these decays to be a background to the search for a narrow A 0 because they mainly decay to two-body final states and have decay widths of 100 MeV/c 2 .…”

We search for the decay Υ (1S) → γA 0 , A 0 → gg or ss, where A 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 6 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) → γA 0 ) • B(A 0 → gg or ss) ranging from 10 −6 to 10 −2 for A 0 masses in the range 0.5 to 9.0 GeV/c 2 .

In the framework of the nonrelativistic quantum chromodynamics factorization formalism, we study the processes of ψ(nS) and Υ(nS) decay into a lepton pair or a charm pair associated with two jets up to the next-to-leading order in velocity expansion. We present the analytic expressions for the differential decay rate to the invariant mass of the lepton pair or charm pair. We find that the ratio of the next-to-leading order short-distance coefficient to the leading order one is in the range from −5.5 to −12.4. The relativistic corrections are so large that they modify the leading order prediction significantly. Utilizing the analytic expressions, we also investigate the relativistic corrections in different kinematic regions and their dependence on the masses of the initial-state quarkonium and the final-state fermion. In addition, we study the momentum distribution of D * + in the process Υ(1S) → ccgg → D * + X.
