Abstract

The present study investigates the feasibility of employing Cherenkov Telescope Array (CTA) technology for the detection of ultra-high-energy (UHE) neutrino-tau particles. By observing the Cherenkov light produced by charged particles resulting from neutrino-tau interactions within mountainous regions, the research seeks to assess the viability of detecting neutrinos within the PeV to EeV energy range. The present paper details the methodology used to calculate the effective detection area and the interaction probabilities of neutrino-tau within the mountains, as well as the flux of Cherenkov photons generated by tau leptons. Furthermore, the present paper addresses the selection of optimal parameters for the telescopes, including mountain dimensions, telescope height, the distance between telescopes, and the distance from the telescopes to the mountain. Strategic placement of the telescopes and the identification of mountain ranges in Algeria that are most suitable for detecting these elusive particles are also discussed. The findings and recommendations for the optimal distribution of telescopes across the selected mountain range are presented, aiming to enhance the detection capabilities for high-energy neutrino-tau particles.
