Simulation Of Double-bang Event Induced By Neutrino In The Atmosphere

We use CORSIKA+Herwig simulation code to produce ultra-high energy neutrino interactions in the atmosphere. Our aimis to reproduce extensive air showers originated by extragalactic tau-neutrinos. For charged current tau-neutrino interactions in the atmosphere, beside the air shower originated from the neutrino interaction it is expected that a tau is created and may decay before reaching the ground. That phenomenon makes possible the generation of two extensive air showers, the so called Double- Bang event. We make a quantitative analysis of the main characteristics of Double-Bang events in the atmosphere and conclude that it may be possible to observe this kind of event in ultra-high energy cosmic ray observatories such as Pierre Auger.5HE PART 213811384Sokolsky, P., (2004) Introduction to Ultrahigh Energy Cosmic Ray Physics, , Westview PressGaisser, T.K., (1990) Cosmic Rays and Particle Physics, , Cambridge University Press, UKYamamoto, T., Mase, K., Takeda, M., Sakaki, N., Teshima, M., Signatures of ultrahigh energy cosmic ray composition from propagation of nuclei in intergalactic photon fields (2004) Astropart.
