Abstract

We study the rare hadronic transitions Υ(2S)→Υ(1S)η and Υ(2S)→Υ(1S)π0 using a sample of 158×106Υ(2S) decays collected with the Belle detector at the KEKB asymmetric-energy e ⁺e^- collider. We measure the ratios of branching fractions (B)B(Υ(2S)→Υ(1S)η)B(Υ(2S)→Υ(1S) π⁺π^-)=(1.99±0.14(stat)±0.11(syst)) ×10^-3 and B(Υ(2S)→Υ(1S)π0)B(Υ(2S) →Υ(1S)π⁺π^-)<2.3×10^-4 at the 90% confidence level (CL). Assuming the value B(Υ(2S) →Υ(1S)π^-π⁺)=(17.92±0.26)%, we obtain B(Υ(2S)→Υ(1S)η)=(3.57±0.25(stat)±0. 21(syst))×10^-4 and B(Υ(2S)→Υ(1S)π0)<4. 1×10^-5(90%CL).

We measure the ratios of branching fractions (B)B(Υ(2S)→Υ(1S)η)B(Υ(2S)→Υ(1S) π+π-)=(1.99±0.14(stat)±0.11(syst)) ×10-3 and B(Υ(2S)→Υ(1S)π0)B(Υ(2S) →Υ(1S)π+π-)<2.3×10-4 at the 90% confidence level (CL). Assuming the value B(Υ(2S) →Υ(1S)π-π+)=(17.92±0.26)%, we obtain B(Υ(2S)→Υ(1S)η)=(3.57±0.25(stat)±0. 21(syst))×10-4 and B(Υ(2S)→Υ(1S)π0)<4. 1×10-5(90%CL).
