Ultrahigh-energy neutrino flux as a probe of large extra-dimensions
arXiv:0705.2029 · doi:10.1088/1475-7516/2007/12/015
Abstract
A suppression in the spectrum of ultrahigh-energy (UHE, >= 10^{18} eV) neutrinos will be present in extra-dimensional scenarios, due to enhanced neutrino-antineutrino annihilation processes with the supernova relic neutrinos. In the n>4 scenario, being n the number of extra dimensions, neutrinos can not be responsible for the highest energy events observed in the UHE cosmic ray spectrum. A direct implication of these extra-dimensional interactions would be the absence of UHE neutrinos in ongoing and future neutrino telescopes.
JCAP accepted version. Included 5, 6 and 7 extra-dimensional cases, and 2 new figures. The conclusion remains unchanged that UHE neutrino flux would be suppressed in large extra-dimensional models
