Resumen:
A neutrino telescopes of a KM3 scale, like IceCube, is a machine designed to study the neutrino flux emitted by astrophysical sources. Using this flux or the neutrino flux produced by the collisions of cosmic ray with the atmospheric nucleons is possible study the neutrino themselves, studying their interaction with nucleons at energies unreachable by colliders or, by using this penetrating flux, study the Earth mass distribution. Since the initial flux is known with several uncertainties, the successful of these studies are dependent of the way in which we define the observable quantity. In this work we discuss the definition and usefulness of the angular observable alpha(E) and the related eta(E) and we study quantitatively their dependence with the initial flux uncertainties. These observable works comparing the flux arriving to telescope from different angular directions. Finally we applied it to the study of the neutrino nucleon interaction and the Earth density.
