TAUDECAY is a library of helicity amplitudes to simulate polarized tau decays, constructed in the FEYN-RULES 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 pairproduced 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.

We have studied the constrained minimal supersymmetric standard model with three right-handed neutrinos, and investigated whether there still is a parameter region consistent with all experimental data/ limits such as the baryon asymmetry of the Universe, the dark matter abundance and the lithium primordial abundance. Using Casas-Ibarra parametrization, we have found a very narrow parameter space of the complex orthogonal matrix elements where the lightest slepton can have a long lifetime, which is necessary for solving the lithium problem. We have studied three cases of the right-handed neutrino mass ratioWe have obtained the mass range of the lightest right-handed neutrino that lies between 10 9 and 10 11 GeV. The important result is that its upper limit is derived by solving the lithium problem and the lower limit comes from leptogenesis. Lepton flavor violating decays such as μ → eγ in our scenario are in the reach of MEG-II and Mu3e.

“…In this case, the dominant stau decays for mτ 1 − mχ0 1 > 160 MeV are expected to be into three particles:χ 0 1 νπ orχ 0 1 νρ. If mτ 1 − mχ0 1 < 1.2 GeV, theτ 1 lifetime is calculated to be so long, in excess of ∼ 100 ns, that it is likely to escape the detector before decaying, and hence would be detectable as a massive, slowly-moving charged particle [43,44].…”
