Guzzo Física, Astronomía y Matemáticas Neutrinos Air showers Pierre Auger Observatory We calculate the possible number of Extensive Air Showers originated by tau neutrinos in FluorescenceDetectors like the ones of the Pierre Auger Observatory. We consider models of production of electron andmuon neutrinos in extra galactic objects and Topological Defects, as well as the possibility of neutrino flavorchange in the propagation of the neutrinos between the source and the Earth. The neutrino cross section wascalculated by the extrapolation of the standard model parton distribution functions until energies of the orderof 1021 eV. However, due to uncertainties in the extrapolation for energies higher than 1012 eV the results arenot robust. We conclude that, depending on the relation between flux and cross section, there is a strict rangeof energy for the tau neutrinos to generate double extensive air showers detectable in Fluorescence Detectors.The tau neutrino energy must be approximately 1018 eV and the event rate can vary some orders of magnitudearound one event per year, depending on the flux-cross section relation and detector characteristics. 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437425 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.2B Vol.37 |
