Abstract
Baikal-GVD is a 1 km3 scale neutrino telescope now under construction in Lake Baikal. The sensitive volume of the detector is currently around 0.5 km3. Muons form through the exchange of W-bosons in the interaction between muon- and partial tau-neutrinos near the telescope. The muons then propagate to great distances in the lake’s water. Reconstructing their trajectory allows us to obtain the most accurate estimate of the direction of neutrinos at telescopes of this type. Angular resolution can be as good as 0.5° for fairly long muon tracks. The current state of affairs in analyzing track events at the Baikal-GVD is discussed.
