Аннотация:
The Ultra-High-Energy(UHE) atmospheric showers with strong influence of the Landau–Pomeranchuk–Migdal (LPM) effect (here after LPM-showers) are exclusively expected to be produced by UHE neutrinos. Studies on the characteristics of the LPM-showers are essentially important to discriminate neutrino-shower (which produced by neutrino interaction) from hadronic shower (initiated by primary hadron). We calculate the LPM-showers initiated by electrons with energies of $10^{18}$ eV to $10^{21}$ eV, using the hybrid method as exactly as possible. Reflecting the change in the air density along the shower trajectories, the variety of the LPM-shower profiles is shown in different cases for their starting points in atmosphere. Through the study of time profiles of air fluorescent photon components from the LPM-showers, the detection capability of UHE neutrinos has also been investigated by the satellite-based experiment with a large acceptance, e.g., the TUS experiment.
