Matter effects in upward-going muons and sterile neutrino oscillations

Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, Volume 517, No. 1-2, Year 2001

The angular distribution of upward-going muons produced by atmospheric neutrinos in the rock below the MACRO detector shows anomalies in good agreement with two flavor vμ → vτ oscillations with maximum mixing and Δm2 around 0.0024 eV2. Exploiting the dependence of magnitude of the matter effect on oscillation channel, and using a set of 809 upward-going muons observed in MACRO, we show that the two flavor vμ → vs oscillation is disfavored with 99% C.L. with respect to vμ → vτ. © 2001 Elsevier Science B.V.
