Single production of excited electrons at future e^-e^+, ep and pp colliders

Abstract

We analyzed the potential of the LC with $\sqrt{s}=0.5$ TeV, LC$\times$LHC based ep collider with $\sqrt{s}=3.74$ TeV and LHC with $\sqrt{s}=14$ TeV to search for excited electrons through transition magnetic type couplings with gauge bosons. The $e^{\star }\to e\gamma$ signal and corresponding backgrounds are studied in detail.
