TeV gravity searches

Understand

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 $E\approx 10^9$ GeV could experience frequent interactions with matter where they lose a very small fraction of their energy.
• We define a consistent model of strong gravity at the TeV scale with just one extra dimension and a first Kaluza-Klein excitation of the graviton of mass around 1 GeV.
