“…However, there are only a few estimates in the literature of TR from cosmic ray showers -either crossing from atmospheric air to a denser medium (e.g. clouds [20] or ground [21]) or emerging from ground into air (a rough estimate is given in [22]). While the methods presented in this paper are of general application, we are mostly motivated by the study of TR emitted when a shower, originated by a UHE neutrino interaction below the Earth surface, escapes the ground into the atmosphere.…”

Coherent radiation at radio frequencies from high-energy showers fully contained in a dense radiotransparent medium -like ice, salt, soil or regolith -has been extensively investigated as a promising technique to search for ultra-high energy (UHE) neutrinos. Additional emission in the form of transition radiation may occur when a neutrino-induced shower produced close to the Earth surface emerges from the ground into atmospheric air. We present the first detailed evaluation of transition radiation from high-energy showers crossing the boundary between two different media. We found that transition radiation is sizable over a wide solid angle and coherent up to ∼ 1 GHz. These properties encourage further work to evaluate the potential of a large-aperture UHE neutrino experiment based on detection of transition radiation.
