Tau air showers detectability with GLAST

TL;DR

This paper explores the potential of the GLAST telescope to detect ultra-high-energy tau air showers generated by cosmic rays, emphasizing its comparable efficiency to larger detectors like AUGER due to lower detection thresholds.

Contribution

It demonstrates the feasibility of using GLAST for detecting tau air showers, highlighting its potential to observe rare high-energy cosmic events within a decade.

Findings

GLAST can detect tau air showers at energies of a few EeV.

Efficiency of GLAST is comparable to AUGER despite smaller effective area.

Potential to observe Glashow resonance signals within ten years.

Abstract

We show that with GLAST there will be the possibility to detect, within the UHECR skimming at atmosphere edges, the showers generated by very high energy upward and horizontal Tau. The effective area, thanks to the large area covered by the showers at 550 Km, is less than that of AUGER, but its efficiency is comparable because the lower detection threshold and the consequent event rate may lead to a few EeV and-or few Glashow resonant signals within a decade.
