Description
We have observed a radiative transition from the psi to a state decaying into Ksub(S)Ksup(+-)πsup(-+), with mass M = 1.44+0sup(.)01sub(-)0sub(.)015 GeV/c2 and width GAMMA = 0.05+0sup(.)03sub(-)0sub(.)02 GeV/c2. 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(psi → γE) x B(E x Kanti Kπ) = (3.6 +- 1.4) x 10-3. (orig.)
