From a high statistics study m(25440 events) of the K+K- system produced in the reaction K-p →K-K+( Λ Σ0) at 18.5 rmGeV/c, evidence is found for a structure with M = 1.87+0.03-0.02 GeV and Γ = 0.16+0.09-0.05 GeV which is partly due to a JPC = 3-- state. This state is interpreted as the "φ like" member of the JPC = 3-- nonet.

Abstract
From a high statistics study m(25440 events) of the K+K- system produced in the reaction K-p →K-K+( Λ Σ0) at 18.5 rmGeV/c, evidence is found for a structure with M = 1.87+0.03-0.02 GeV and Γ = 0.16+0.09-0.05 GeV which is partly due to a JPC = 3-- state. This state is interpreted as the "φ like" member of the JPC = 3-- nonet.
