الوصف: We have observed a radiative transition from the ψ to a state decaying into K S K ± π ∓ , with mass M = 1.44 −0.015 +0.01 GeV/ c 2 and width Γ = 0.05 −0.02 +0.03 GeV/ c 2 . We tentatively identify this state as the E(1420). Assuming that this state is an isospin singlet, we have determined the branching fraction product B(ψ → γ E ) × B( E × K K π) = (3.6 ± 1.4) × 10 −3 .
