In scenarios with extra dimensions the gravitational interaction may become strong at TeV energies. This could modify the $\nu$$N$ cross section and imply distinct signals at neutrino telescopes. In particular, cosmogenic neutrinos of…

Lowering the string scale in the TeV region provides a theoretical framework for solving the mass hierarchy problem and unifying all interactions. The apparent weakness of gravity can then be accounted by the existence of large internal…
