摘要It has been controversial whether eta(b) can be discovered in Tevatron Run 2 through the decay eta(b) -> J/psi J/psi followed by J/psi -> mu(+) mu(-). I clear this controversy by an explicit calculation which predicts Br[eta(b) -> J/psi J/psi] to be of order 10(-8). It is concluded that observing eta(b) through this decay mode in Tevatron Run 2 may be rather unrealistic. The eta(b) may be observed in the forthcoming CERN LHC experiments through the 4-lepton channel, if the background events can be significantly reduced by imposing some kinematical cuts. By some rough but plausible considerations, I find that the analogous decay processes eta(b) -> VV, D*(D) over bar* also have very suppressed branching ratios; nevertheless it may be worth looking for eta(b) at LHC and Super B factory through the decay modes eta(b) -> K-S K-+/- pi(-/+) D*(D) over bar D.
