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 γpp̅ . We present branching ratio measurements for the decay modes Υ(1S)→γf_2(1270), Υ(1S)→γf′_2(1525), and Υ(1S)→γK^+K^-; helicity production ratios for f_2(1270) and f′_2(1525); upper limits for the decay Υ(1S)→γf_J(2200), with f_J(2220)→π^+π^-, K^+K^-, pp̅ ; and an upper limit for the decay Υ(1S)→γX(1860), with X(1860)→γpp̅ .
