Description
Summary:The spectrum of the s s ¯ mesons is studied performing a phenomenological analysis of the Regge trajectories defined for the excitation energies. For the ϕ ( 3 3 S 1 ) state the mass M ( ϕ ( 3 S ) ) = 2100 ( 20 )  MeV and the leptonic width Γ ee ( ϕ ( 3 S ) ) = 0.27 ( 2 )  keV are obtained, while the mass of the 2 3 D 1 state, M ( ϕ ( 2 3 D 1 ) ) = 2180 ( 5 )  MeV, appears to be in agreement with the mass of the ϕ ( 2170 ) resonance, and its leptonic width, Γ ee ( 2 3 D 1 ) = 0.20 ± 0.10  keV, has a large theoretical uncertainty, depending on the parameters of the flattened confining potential.
