TL;DR: In this article, a measurement of the flux of neutrino-induced upgoing muons ( ν >∼ 100 GeV) using the MACRO detector is presented, where the ratio of the observed to expected events integrated over all zenith angles is 0.74 ± 0.036 (stat) ±0.13 (theoretical).

TL;DR: 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.
Journal ArticleDOI
New precision tests of the Einstein equivalence principle from SN1987A
TL;DR: The relativistic time delays of the photons and neutrinos from SN1987A caused by the gravitational field of the authors' Galaxy are compared, and it is shown that they are equal, to an accuracy of approximately 0.2% of the predicted delay.
