Abstract 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 ν μ → ν τ oscillations with maximum mixing and Δm 2 around 0.0024 eV 2 . 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 ν μ → ν s oscillation is disfavored with 99% C.L. with respect to ν μ → ν τ .
