000002080 520__ $$aWe present the measurement of the Belle II track reconstruction efficiency and Monte Carlo efficiency correction factors using τ-pair events, in which one τ lepton decays leptonically ( τ → lνν , l = e, μ) while the other decays hadronically into three charged pions ( τ → 3πν + nπ0). These measurements are performed using the e+e- collision data recorded during the early Phase III of data taking.
