Description

A new method is proposed for detection of chisub(b) states which is using the chisub(b) → phiphi decay. The obtained estimate for relative probability of the decay chisub(b)(0++) → phiphi is Br(0sub(b)sup(++) → phiphi) approximately 3x10-5. The calculations have been performed in the framework of the QCD perturbation theory (graphs of the order of αsub(s)sup(4) are taken into account). Estimated ratios of the signal concerned to the background due to continuum of J/phi meson pairs produced in hadron-hadron collisions are about unity at a mass resolution of ΔMsub(phiphi) approximately 200 MeV
