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 ΓeeR⋅Br(R→hadr)<120 eV has been obtained (at 90% C.L.).
