Abstract

A search for the rare decay η→e+e- is performed using the inverse process e+e-→η in the decay mode η→π0π0π0. We analyze data with an integrated luminosity of 654 nb-1 accumulated at the VEPP-2000 e+e- collider with the SND detector at the center-of-mass energy E=mηc2≈548 MeV, and set the upper limit B(η→e+e-)<7×10-7 at the 90% confidence level.
