Abstract
Evidence is presented for a narrow state, called , in the decay modes J, K+K-, and KS0KS0. In the K+K- mode, the has a mass of 2.2300.0060.014 GeV/c2, a width of =0.026-0.016+0.020 0.017 GeV/c2, a product branching ratio of (4.2-1.4+1.70.8)×10 -5, and a statistical significance of 4.5 standard deviations. In the KS0KS0 mode, it has a mass of 2.2320.0070.007 GeV/c2, a width of =0.018-0.015+0.023 0.010 GeV/c2, a product branching ratio of (3.1-1.3+1.60.7)×10 -5, and a statistical significance of 3.6 standard deviations. Limits on decay to other final states are presented.
