Search for the Lepton Number Violation Decay Φ → Π⁺π⁺e^-e^- Via <i>j</i>/ψ → Φη

Using an electron-positron collision data sample corresponding to (1.0087 +/- 0.0044) x 10(10) J/psi events collected using the BESIII detector at the BEPCII collider, we firstly search for the lepton number violation decay phi -> pi(+)pi(+)e(-)e(-) via J/psi -> phi eta. No obviously signals are found. The upper limit on the branching fraction of phi -> pi(+)pi(+)e(-)e(-) is set to be 1.3 x 10(-5) at the 90% confidence level.
