Measurement of the branching fractions and mass spectra for τ lepton decays including at Belle

We report a study of τ lepton decays involving with a 669 fb−1 data sample accumulated with the Belle detector at the KEKB asymmetric-energy e+e− collider. The branching fractions have been measured for the , , , , and decays. We also provide the unfolded mass spectra for and .
