Neutrino Flux Bounds, Event Rates, and their Implications for an
Inner Earth Tomography
During propagation through the Earth, neutrino-nucleon and
neutrino-electron interactions lead to changes in a given neutrino
spectrum. Using the latest CTEQ6DIS parton distribution functions and
a discretized energy grid, we show that these changes can be computed
(semi-)analytically, and we apply the formalism thus found in order to
discuss the implications for the neutrino event rates (in water-based
Cherenkov detectors) of various source models. Here we especially
consider the flux bounds given by Waxman & Bahcall and by Mannheim,
Protheroe & Rachen. In addition, we investigate the corresponding
limitations for an inner Earth tomography by means of ultrahigh energy
neutrinos.
