“…where f and f ′ are coupling constants, has been used extensively in a number of phenomenological papers which presents ideas on searching for excited fermion production and decay to final state gauge bosons in e + e − , pp, ep, and eγ collisions [4,5,6]. Direct searches for lepton compositeness has been done extensively at LEP [7] and HERA [8], each with no discovery, but with ever more sensitive limits. Unfortunately, only direct searches for quark compositeness have been done at the Fermilab Tevatron [9].…”

This letter presents a study of prospects of searching for excited leptons during Run II of the Fermilab Tevatron. We concentrate on single and pair production of excited electrons in the photonic decay channel in one CDF/DØ detector equivalent for 2 fb −1 . By the end of Run IIa, the limits should be easily extended beyond those set by LEP and HERA for excited leptons with mass above about 190 GeV.

“…An excited neutrino with a mass less than 213 GeV by H1 collaboration at the HERA has excluded assuming f /Λ = 1/m * and f = f ′ [6]. In the literature, the excited neutrinos have been experimentally or theoretically examined at the HERA [7][8][9][10][11], LEP [12][13][14], and LHC [15][16][17].…”

We analyze the single and pair production of excited neutrinos at the CLIC through the processes e + e − → ν * ν , e + e − → e + γ * e − → e + ν * W − , and e + e − → e + γ * γ * e − → e + ν * ν * e − (γ * is the Weizsacker-Williams photon). We examine comprehensively the excited neutrino signal and corresponding backgrounds to obtain limits on excited neutrino mass for various values of the integrated luminosity and center-of-mass energy. We show that the obtained bounds are more restricted than current experimental bounds. * mkoksal@cumhuriyet.edu.tr

A search for charged and neutral excited leptons is performed in 217 pb−1 of e+e− collision data collected with the L3 detector at LEP at centre-of-mass energies from 202 up to 209 GeV. The pair- and single-production mechanisms of excited electrons, muons and taus, as well as of excited electron-, muon- and tau-neutrinos, are investigated and no signals are detected. Combining with L3 results from searches at lower centre-of-mass energies, gives improved limits on the masses and couplings of excited leptons
