Neutrino-oscillation search with cosmic-ray neutrinos

Journal Article · · Phys. Rev. D; (United States)
A sensitive search for neutrino oscillations involving ..nu../sub e/, ..nu../sub ..mu../, and ..nu../sub tau/ may be provided by measurements of the ratio of the total interaction rates of upward- and downward-going cosmic-ray neutrinos within a massive (approx.10 kton) detector. Assuming mixing between all pairs of ..nu../sub e/, ..nu../sub ..mu../, and ..nu../sub tau/, the experiment is capable of observing time-averaged probabilities

/sub t/ and

/sub t/ of magnitude set by mixing strengths corresponding to, e.g., the d- to s-quark mixing strength, and of reaching the limit ..delta..m/sub i/j/sup 2/equivalentVertical Barm/sub i//sup 2/-m/sub j//sup 2/Vertical Barroughly-equal10/sup -4/ eV/sup 2/, where m/sub i/, and m/sub j/ are neutrino mass eigenstates, and P/sub e/tau and P/sub mutau/ are the probabilities for ..nu../sub e/ and ..nu../sub ..mu../, respectively, to oscillate into ..nu../sub tau/ after traversing a distance Lroughly-equal diameter of the Earth. Possible ambiguities may be resolved through comparison of the ratios N/sub e//N/sub ..mu../ for the upward- and downward-going neutrinos.
