Diffuse neutrino flux measurements with the Baikal-GVD neutrino telescope

Abstract

The Baikal-GVD neutrino telescope collaboration reports observing the diffuse cosmic neutrino flux. Relying on cascade events produced predominantly by electron and tau neutrinos, they observe a significant excess of events over what is expected from the atmospheric neutrino background. The power law fit of the flux and the observation itself are consistent with and a significant independent confirmation of the landmark results of IceCube.
