摘要We propose that the radiative decay process, eta(b) -> J/psi gamma, may serve as a clean searching mode for eta(b) in hadron collision facilities. By a perturbative QCD calculation, we estimate the corresponding branching ratio to be of order 10(-7). Though very suppressed, this radiative decay channel in fact has larger branching ratio than the hadronic decay process eta(b) -> J/psi J/psi, which was previously hoped to be a viable mode to search for eta(b) in Tevatron Run 2. The discovery potential of eta(b) through this channel seems promising in the forthcoming LHC experiments, and maybe even in Tevatron Run 2, thanks to the huge statistics of eta(b) to be accumulated in these experiments. The same calculational scheme is also used to estimate the branching ratios for the processes eta(b) (eta(c)) -> phi gamma.
