Abstract
Using data obtained with the CLEO III detector, running at the Cornell Electron Storage Ring (CESR), we report on a new study of exclusive radiative Υ(1S) decays into the final states γπ+π-, γK+K-, and γpp̄. We present branching ratio measurements for the decay modes Υ(1S)→γf2(1270), Υ(1S)→γf2′(1525), and Υ(1S)→γK+K-; helicity production ratios for f2(1270) and f2′(1525); upper limits for the decay Υ(1S)→γfJ(2200), with fJ(2220)→π+π-, K+K-, pp̄; and an upper limit for the decay Υ(1S)→γX(1860), with X(1860)→γpp̄.
