Diffuse neutrino flux measurements with the Baikal-GVD neutrino telescope
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 $\gamma_{astro}=2.64^{+0.09}_{-0.11}$ and the flux normalization $\Phi_{astro}=4.42^{+2.31}_{-1.29}\times10^{-18}~GeV^{-1}cm^{-2}s^{-1}sr^{-1}$ per one flavor at 100 TeV. These results are broadly consistent with IceCube measurements.
