Excited Neutrino at Next Linear Colliders

Abstract

The possibility of single and pair excited neutrino production in high energy e+e-, gamma-e and gamma-gamma collisions on linear colliders is studied. The integrated cross sections of these subproceses are calculated. Special attention is paid to search for excited neutrino in e-gamma --> W- W+ e process. Lower limits for the compositeness parameter estimated which will be available on the experiments at VLEPP, SLAC, JLC and DESY future linear colliders.
