Abstract content

Neutrino telescopes allow the collection of large samples of multi-TeV neutrinos. Above a few tens of TeV, since the neutrino cross section increases with energy, the increasing absorption of neutrinos crossing the Earth modifies the energy spectrum of atmospheric neutrinos in a zenith-dependent way. These effects can be quantified using the high-purity neutrino samples collected with ANTARES, though the precision of the measurement is limited by statistics. The next-generation neutrino telescope in the Mediterranean Sea, KM3NeT/ARCA, already under construction, will provide a much more precise measurement. Preliminary results will be presented in this contribution for both experiments.
