Neutrino–nucleon cross section at intermediate energy from KM3 neutrino telescopes

Abstract

The capability of a KM3 neutrino telescope to bounds the neutrino nucleon cross section in theintermediate energy range (105 GeV < E < 107 GeV ) is studied. We use an observable which only makesuse of the upward-going neutrino °ux, so that the Earth ¯lters the atmospheric muons, and it is onlyweakly dependent on the initial astrophysical °ux uncertainties and experimental systematic. In order tostudy the sensitivity to departures from the standard model we have considered a cross section which isa version perturbated of the standard model one, dependent of two parameters. We present the results asregions for the allowed values for both, the parameters space and the cross section.
