Resumen:
The capability of a KM3 neutrino telescope to bounds the neutrino nucleon cross section in the intermediate energy range (105 GeV < E < 107 GeV ) is studied. We use an observable which only makes use of the upward-going neutrino flux, so that the Earth filters the atmospheric muons, and it is only weakly dependent on the initial astrophysical flux uncertainties and experimental systematic. In order to study the sensitivity to departures from the standard model we have considered a cross section which is a version perturbated of the standard model one, dependent of two parameters. We present the results as regions for the allowed values for both, the parameters space and the cross section.
