Özet

We study the potential of future high energy e(+)e(-) colliders to probe excited neutrino signals in different channels coming from the single production process via gauge interactions. We calculate the production cross section, decay widths, and branching ratios of excited spin-3/2 neutrinos according to their effective currents and we compare them with those of the spin-1/2 ones. The signals and corresponding backgrounds are examined in detail to get accessible limits on the masses and couplings of excited spin-3/2 neutrinos.
