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 (1S) decays into the final states +-, K+K-, and pp. We present branching ratio measurements for the decay modes (1S)f2(1270), (1S)f2(1525), and (1S)K+K-; helicity production ratios for f2(1270) and f2(1525); upper limits for the decay (1S)fJ(2200), with fJ(2220)+-, K+K-, pp; and an upper limit for the decay (1S)X(1860), with X(1860)pp. 2006 The American Physical Society.
