$τ^{-} \to η π^{-} π^{0} ν_{τ}$ and $σ (e^{+} e^{-} \to η π^{+} π^{-})$ at low energies

P. Roig

We analyze the hadronization structure of $τ \to η π^{-} π^{0} ν_{τ}$ decays. In the isospin limit only the vector current contributes to this process. We compute the relevant form factor…

tau -> pi pi pi nu_tau decays and the a_1(1260) off-shell width revisited

D. Gomez Dumm, P. Roig, A. Pich +1

The tau -> pi pi pi nu_tau decay is driven by the hadronization of the axial-vector current. Within the resonance chiral theory, and considering the large-Nc expansion, this proces…
