The Circular Electron Positron Collider (CEPC) is a future Higgs factory
proposed by the Chinese high energy physics community. It will operate at a
center-of-mass energy of 240-250 GeV. The CEPC will accumulate an integrated
luminosity of 5 abβ1 in ten years' operation. With GEANT4-based full
simulation samples for CEPC, Higgs boson decaying into electron pair is studied
at the CEPC. The upper limit of B(Hβe+eβ) could reach
0.024\% at 95\% confidence level. The signal process is generated by MadGraph,
with Initial State Radiation (ISR) implemented, as a first step to adjust
MadGraph for a electron positron Collider.Comment: Accepted version by J.P.
