Abstract:
'Baikal-GVD is a cubic-kilometer scale neutrino detector beingrnconstructed in Lake Baikal. After the deployment campaign in springrn2020 the telescope includes over 2000 optical modules distributedrnamong 56 strings. Effective volume for the detection of high-energyrncharged particle cascades constitutes 0.35 km^3. Muon (anti)neutrinorninteractions in the vicinity of the detector through the W bosonrnexchange are accompanied by muon tracks. Reconstructed direction ofrnthe muon track is the most precise probe of the neutrino directionrnattainable in Cerenkov neutrino telescopes. Reconstruction techniquesrnadopted by Baikal-GVD include methods for the rejection of noise duernto water chemilumenescence and track parameter reconstruction based onrnchi^2 minimisation. Muon reconstruction performance is discussed in thernpresent report. Performance metrics of the muon reconstruction arernstudied using realistic Monte Carlo (MC) simulation of the detector.rnThe algorithms are applied to real data from Baikal-GVD and thernresults are compared with simulations.'
