TeV gravity searches
Abstract
In scenarios with extra dimensions the gravitational interaction may become strong at TeV energies. This could modify the cross section and imply distinct signals at neutrino telescopes. In particular, cosmogenic neutrinos of E≈ 109 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. We describe the collisions at transplanckian energies (multigraviton exchange, graviton emission and black hole formation) as well as the possible signature of these processes at km3 telescopes and their impact in cosmogenic neutrino searches.
