Abstract

The detection of a ν τ flux in a neutrino telescope would provide a way to measure the cosmic flux without the background of the atmospheric ν μ ’s. Given that effects of new physics could alter the flux arriving at the detector, in this work we consider, as a particular scenario, the effects of leptoquarks on the propagation in the Earth of tau neutrinos. We calculate their contribution to the neutrino–nucleon interaction and their effect on the transport. We show the resulting ν τ flux and compare it with the ν μ flux after through the planet. Finally, we obtain the 90 % C.L. region (Sensitivity Region) where neutrino telescopes will be sensible to the leptoquark effects.
