| Résumé : | We present a search for excited and exotic electrons (e*) decaying to an electron and a photon, both with high transverse momentum. We use 202 pb -1 of data collected in pp̄ collisions at √s = 1.96 TeV with the Collider Detector at Fermilab II detector. No signal above standard model expectation is seen for associated ee* production, We discuss the e* sensitivity in the parameter space of the excited electron mass M e* and the compositeness energy scale Λ. In the contact interaction model, we exclude 132 GeV/c 2 < M e* < 879 GeV/c 2 for Λ = M e* at 95% confidence level (C.L.). In the gauge-mediated model, we exclude 126 GeV/c 2 < M e* < 430 GeV/c 2 at 95% C.L. for the phenomenological coupling f/Λ ≈ 10 -2GeV -1. © 2005 The American Physical Society. |
