Description

In a study of the radiative decay J/Ψ #-> # γΦΦ #-> # γK+K-K+K-, from the 8.6 million J/Ψ produced in the DM2 experiment at DCI, we found a large production of events with ΦΦ mass below the ηc. The branching ratio, for mΦΦ < 2.9 GeV/c2, is BR(J/Ψ #-> # γΦΦ) = (3.1± 0.3± 0.6) x 10-4. The angular analysis of the events with Φ Φ mass below 2.5 GeV/c2 is consistent with a 2++ assignment. An enhancement near 2.2 GeV/c2 shows a preferred spin-parity JP = 0-
