Abstract

Baikal-GVD is a 1 km3 – scale neutrino telescope being constructed in Lake Baikal. Presently the sensitive volume of the detector constitutes about 0.5 km3. Muons being produced in muon and partly tau-neutrino interactions in the vicinity of the telescope ongoing through the W-boson exchange propagate at large distances in Lake water. Reconstructed muon trajectory provides the most precise probe of the neutrino direction attainable at large-volume neutrino telescopes. Angular resolution can be as good as 0.5° for muon tracks of sufficient length. The status of the data analysis in the muon channel at the Baikal-GVD is discussed.
