Abstract

We have measured branching fractions of hadronic τ-decays involving an η meson, using 490 fb−1 of data collected with the Belle detector at the KEKB asymmetric-energy collider: , , , , and . Thoese results are compared with theoretical calculations based on the CVC hypothesis or the VDM model. [Copyright &y& Elsevier]
