Search for eta b at CDF

The {eta}{sub b} (1S) is the J{sup PC} = 0{sup {-+}} b{bar b} ground state, and has not yet been experimentally observed. Theorists have recently suggested that it could be observed at the Fermilab Tevatron through its decay to J/{psi}J/{psi}, if not in the 1992-96 (''Run 1'') dataset, then in Run 2. This article describes a search for this particle at CDF in Run 1 using this decay channel. A small cluster is seen, with 7 events where 1.8 events are expected from background. The statistical significance is estimated to be 2.2{sigma}, and an upper limit is set on the product of cross section and branching fractions.
