WebJun 7, 2024 · The hadronic \tau decay is a very useful tool to investigate the nature of the light hadrons. The initial state being lepton allows to study the strong decays of the final state hadrons in a clean manner. The hadrons being produced from the W boson provides a valuable information on the vector and the axial vector couplings of the hadrons.
