Further experimental studies of two-body radiative Upsilon decays

Abstract:

Continuing our studies of radiative Υ decays, we report on a search for Υ→γη and fj(2220) in 61.3 pb-1 of e+e- data taken with the CLEO II detector at the Cornell Electron Storage Ring. For the γη search the three decays of the η meson to π+ π- π0, π0 π0 π0, and γγ were investigated. We found no candidate events in the (3 π)0 modes and no significant excess over expected backgrounds in the γγ mode to set a limit on the branching fraction of B(Y→γη)< 2.1 × 10-5 at 90% C.L. The three charged...
