Probing the absolute density of the Earth's core using a vertical neutrino beam

摘要

We demonstrate that one could measure the absolute matter density of theEarth's core with a vertical neutrino factory baseline at the per cent levelfor $\sin^2 2 \theta_{13} \gtrsim 0.01$, where we include all correlations withthe oscillation parameters in the analysis. We discuss the geographicalfeasibility of such an approach, and illustrate how the results change as afunction of the detector location. We point out the complementarity togeophysics.
