Matter effects in upward-going muons and sterile neutrino oscillations

Published

Journal Article

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 v μ → v 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 v μ → v s oscillation is disfavored with 99% C.L. with respect to v μ → v τ . © 2001 Elsevier Science B.V.
