Advantages of a Very Long Baseline
? neutrino oscillations result from the factor
sin2(Dm322 L / 4E) modulating the n flux for
each flavor (here nm disappearance) ? the
oscillation period is directly proportional to
distance and inversely proportional to
energy ? with a very long baseline actual
oscillations are seen in the data as a
function of energy ? the multiple-node structure
of the very long baseline allows the
Dm322 to be precisely measured by a
wavelength rather than an amplitude (reducing
systematic errors)
