Resumen:
High energy neutrinos play a very important role for the understanding
of the origin and propagation of ultra high energy cosmic rays (UHECR).
They can be produced as a consequence of the hadronic interactions
suffered by the cosmic rays in the acceleration regions, as by products
of the propagation of the UHECR in the radiation background and as a
main product of the decay of super heavy relic particles. A new era of
very large exposure space observatories, of which the JEM-EUSO mission
is a prime example, is on the horizon which opens the possibility of
neutrino detection in the highest energy region of the spectrum. In the
present work we use a combination of the PYTHIA interaction code with
the CONEX shower simulation package in order to produce fast
one-dimensional simulations of neutrino initiated showers in air. We
make a detail study of the structure of the corresponding longitudinal
profiles, but focus our physical analysis mainly on the development of
showers at mid and high altitudes, where they can be an interesting
target for space fluorescence observatories.
