Investigation on the neutrino induced muons from active galactic nuclei

The fluxes of neutrino induced muons at different zenith angles have been c alculated using the high energy diffused neutrino spectra emitted from blaz ars. We have used the standard formulation developed by Gaisser based on ch arge-current interactions in rock and the QED-based energy loss formulation to estimate the spectra of neutrino induced muons. The energy spectra of n eutrino flux generated from blazars has been taken from the model calculati ons of Protheroe. The latest charge-current and total interaction cross-sec tions at ultrahigh energies from Kwiecinski et al. have been used to find t he probability of muon generation from neutrinos and the loss of neutrinos during propagation through the Earth. We find that our derived horizontal n eutrino induced muon energy spectra expected from blazar model of Protheroe is comparable with the upper limits as predicted by SOUDAN 2 experiment.
