Narrow Results

We analyze the single and pair production of excited neutrinos at the CLIC through the processes , e⁺e^-→e⁺γ* e^- →e⁺ν*W^- and (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.
