TauDecay swMATH ID: 33103 Software Authors: Hagiwara, K.; Li, T.; Mawatari, K.; Nakamura, J. Description: TauDecay: a library to simulate polarized tau decays via FeynRules and MadGraph5. TAUDECAY is a library of helicity amplitudes to simulate polarized tau decays, constructed in the FEYNRULES and MADGRAPH5 framework. Together with the leptonic mode, the decay library includes the main hadronic modes, τ→ν τ +π, 2π, and 3π, which are introduced as effective vertices by using FEYNRULES. The model file allows us to simulate tau decays when the on-shell tau production is kinematically forbidden. We also demonstrate that all possible correlations among the decay products of pair-produced taus through a Z boson and a scalar/pseudoscalar Higgs boson are produced automatically. The program has been tested carefully by making use of the standard tau decay library TAUOLA.
