Correlations between ?13 and ?23 in a very long baseline neutrino oscillation experiment
Physical Review C
A very long baseline experiment, with L/E of 1.6×104 m/MeV, has been proposed as the ideal means to measure ?13, including its sign, for neutrino energies less than 50 MeV. Higher energies require consideration of the Earth MSW effect. Approximating a constant density mantle, we examine the ?e-?? and ??-?? oscillation channels at very long baselines with particular focus upon the deviation of ?23 from maximal mixing and the sign of ?13. It is demonstrated that measurements of these oscillation channels in this region are sensitive to ?13, including its sign, and to ?23, including its octant, with a significant correlation between the value of ?13 and the difference of ?23 from maximal mixing.
