Search for excited electrons through $γγ$ scattering

We study the potential of $γγ$ option of future high energy linear $e^{+}e^{-}$ colliders to search for excited electrons with spin-1/2. We calculate single production cross sections, give the angular distributions and $f-m^*$ contour plots for $\sqrt{s}=0.5$ TeV and $\sqrt{s}=3$ TeV both using the standard (tree level) couplings and anomal couplings.
