AbstraktAbstract
We present measurement of the diffuse astrophysical neutrino flux using Baikal-GVD cascade data collected between April 2018 to March 2024. The diffuse astrophysical neutrino flux is detected with a statistical significance of 5.1 sigma. Assuming a single power law model of the astrophysical neutrino flux with identical contribution from each neutrino flavor, the following best-fit parameter values are found: the spectral index γastro = 2.64+−00.0911 and the flux normalization Φastro = 4.42+−21.3129 × 10−18 GeV−1cm−2s−1sr−1 per one flavor at 100 TeV. These results are broadly consistent with IceCube measurements.
