Search for Neutrino Generated Air Shower Candidates with Energy More than 5$\cdot$10$^{18}$ eV and Zenith Angle $\theta$ $\geq$ 50$^\circ$

TL;DR

This study searches for ultra-high-energy neutrino-induced air showers with large zenith angles using data from scintillation detectors, aiming to identify neutrino events and improve detection methods.

Contribution

The paper introduces an analysis of extensive detector data to identify neutrino-induced air showers and proposes improved methodologies for detecting highly inclined showers.

Findings

No neutrino-induced air showers detected in preliminary analysis

Large datasets analyzed for neutrino signatures

Further analysis needed with improved detection methods

Abstract

Neutrino air showers can be formed in any part of the atmosphere passing a long was in the matter due to its physical properties. In general, air showers produced by neutrinos are highly inclined and formed near the ground level, i.e. young showers. Therefore, one should expect a large number of peaks in the signal of such air showers [1, 2, 3]. The goal of our work is to search for air shower candidates produced by neutrino. For this purposes, we analyzed large amount of data from scintillation detectors with different area and energy thresholds [1, 2]. Preliminary analysis of Yakutsk array data indicated the absence of air shower produced by neutrino, but it does not mean that such air showers does not exist. It is going to need a further analysis of highly inclined showers. In order to do that improved methodology for recording and processing of air showers required.
