Analysis of excited neutrinos at the CLIC

Abstract

We analyze the single and pair production of excited neutrinos at the CLIC through the processes $e^{+}{e}^{-}\to {\nu }^{\ast }\bar{\nu }$, $e^{+}{e}^{-}\to e^{+}{\gamma }^{\ast }{e}^{-}\to e^{+}{\nu }^{\ast }{W}^{-}$, and $e^{+}{e}^{-}\to e^{+}{\gamma }^{\ast }{\gamma }^{\ast }{e}^{-}\to e^{+}{\nu }^{\ast }{\bar{\nu }}^{\ast }{e}^{-}$ (${\gamma }^{\ast }$ 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.
