Search for narrow resonances in e+e- annihilation between 1.85 and 3.1 GeV with the KEDR detector
We report results of a search for narrow resonances in e+e- annihilation at center-of-mass energies between 1.85 and 3.1 GeV performed with the KEDR detector at the VEPP-4M e+e- collider. The upper limit on the leptonic width of a narrow resonance Γee R.Br(R→hadr)<120 eV has been obtained (at 90% C.L.). © 2011 Elsevier B.V.
