Abstract

We analyze the single and pair production of excited neutrinos at the CLIC through the processes e(+)e(-) -> upsilon*upsilon(-) -> e(+) e -. e+gamma*e(-) -> e(+)upsilon*W- and e(+)e(-) -> e(+)gamma*gamma*e(-) -> e(+) upsilon*(upsilon) over bar *e(-) (gamma* s 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.
