Title: Search for light tetraquark states in Y ( 1 S ) and Y ( 2 S ) decays

Abstract

We search for the J PC = 0 – – and 1 +– light tetraquark states with masses up to 2.46 GeV/c 2 in Υ(1S) and Υ(2S) decays with data samples of (102 ± 2) million and (158 ± 4) million events, respectively, collected with the Belle detector. No significant signals are observed in any of the studied production modes, and 90% credibility level (C.L.) upper limits on their branching fractions in Υ(1S) and Υ(2S) decays are obtained. The inclusive branching fractions of the Υ(1S) and Υ(2S) decays into final states with f 1(1285) are measured to be B(Υ(1S) → f 1(1285) + anything) = (46 ± 28(stat) ± 13(syst)) × 10 –4 and B(Υ(2S) → f 1(1285) + anything) = (22 ± 15(stat) ± 6.3(syst)) × 10 –4. The measured χ b2 → J/ψ + anything branching fraction is measured to be (1.50 ± 0.34(stat) ± 0.22(syst)) × 10 –3, and 90% C.L. upper limits for the χ b0,b1 → J/ψ + anything branching fractions are found to be 2.3 × 10 –3 and 1.1 × 10 –3, respectively. For B(χ b1 → ω + anything), the branching fraction is measured to be (4.9 ± 1.3(stat) ± 0.6(syst)) ×more » 10 –2. All results reported here are the first measurements for these modes.« less
