Description
We explore the new physics scenarios case by case that can
modify the interactions between neutrinos and matter at future tau neutrino telescopes. Recent progress of multimessenger astronomy, especially the ultra-high-energy neutrino observations at IceCube, has sparked a campaign towards neutrino detection at extreme energies around
the Greisen-Zatsepin-Kuzmin cutoff around 10^9 GeV. A promising class of such observatories is the tau neutrino telescope. The neutrino as an elusive particle, on the one hand, can point directly towards the cosmic accelerators, and on the other hand, provides a promising portal to new
physics. While the tau sector is difficult to probe in the laboratory, the tau neutrino telescopes are congenitally sensitive to the new physics lying in the third family. Among many models, we identify two new physics cases at the tree level that can give large contributions to neutrino cross sections while staying within laboratory constraints: the
charged Higgs and the leptoquark models. We follow the realistic experimental configurations of the telescopes as close as possible and perform the $\chi^2$ analysis on the energy and angular distributions of the tau events. By numerically solving the propagation equations of
neutrino and tau fluxes in matter, we have obtained the sensitivities of future tau neutrino telescopes, GRAND, POMMEA and Trinity, to the charged Higgs and leptoquark models.
