Abstract
We study the Υ(1S) radiative decays to γπ+π− and γK+K− using data recorded with the BABAR detector operating at the SLAC PEP-II asymmetric-energy e+e− collider at center-of-mass energies at the Υ(2S) and Υ(3S) resonances. The Υ(1S) resonance is reconstructed from the decay Υ(nS)→π+π−Υ(1S), n=2, 3. Branching fraction measurements and spin-parity analyses of Υ(1S) radiative decays are reported for the I=0 S-wave and f2(1270) resonances in the π+π− mass spectrum, the f′2(1525) and f0(1500) in the K+K− mass spectrum, and the f0(1710) in both.
