Brief Reports γ(1 S) →γf2′(1525); F2′(1525)→ KS0KS0, decays.

Abstract:

We report on a study of exclusive radiative decays of the Υ(1S) resonance into a final state consisting of a photon and two KS0 candidates. We find evidence for a signal for Υ(1S)→γf2′(1525); f2′(1525)→γKS0KS0, at a rate B(Υ(1S) →γf2′(1525))=(4.0±1.3±0.6)×10-5, consistent with previous observations of Υ(1S)→γf2′(1525) ; f2′(1525)→K+K-, and isospin. Combining this branching fraction with existing branching fraction measurements of Υ(1S)→γf2′(1525) and J/ψ→γf2′(1525), we obtain the ratio of bra...
