Description
We considered the longest baseline neutrino oscillation available, crossing mostof the Earth diameter, may improve the measurement and disentangle at best any hypothetical CPT violation within MINOS bounds, while testing at highest rate tau and even the anti tau appearance. The μ and anti muon disappearance correlated with tau
appearance is considered for those largest distances. We thus propose a beam through the Earth, within an OPERA-like experiment from CERN (or FermiLAB), in the direction of ICECUBE-DeepCore detector at the South Pole. The ideal energy lay at 21 GeV energy, to test the disappearance or (for any tiny CPT violation) the partial neutrino μ appearance. The tau appearance signal is above (or within) 10 sigma in a year, even for 1% OPERA-like experiment. Peculiar configurations for theta 13 and hierarchy neutrino mass
test may also be better addressed by a Deep Core-PINGU array detector beaming μ neutrino and observing an electon one at 6 GeV energy windows.
