The experimental data from VENUS, TOPAS, OPAL, DELPHI, ALEPH and L3 Collaborations collected 1989 to 2003 are applied study the quantum electrodynamics (QED) framework through direct contact interaction term approach, using annihilation reaction e+e−→γγ(γ). analysis involves performing a χ2-test detect presence of an excited electron e*, evidence non-point like behavior in e+e− zone. yields com...
