New upper limit on the decay η→e+e-

We have searched for the rare decay of the η meson η→e+e- using the CLEO II detector. The η's were produced in e+e- collisions with 10 GeV center-of-mass energy at the Cornell Electron Storage Ring (CESR). We find with 90% confidence the upper limit on the branching fraction B(η→e+e-) <...
