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 Upsilon(1S) decays into the final states gamma pi(+)pi(-), gamma K+K-, and gamma p (p) over bar. We present branching ratio measurements for the decay modes Upsilon(1S)->gamma f(2)(1270), Upsilon(1S)->gamma f '(2)(1525), and Upsilon(1S)->gamma K+K-; helicity production ratios for f(2)(1270) and f '(2)(1525); upper limits for the decay Upsilon(1S)->gamma f(J)(2200), with f(J)(2220)->pi(+)pi(-), K+K-, p (p) over bar; and an upper limit for the decay Upsilon(1S)->gamma X(1860), with X(1860)->gamma p (p) over bar.
