1. Effective-field theory analysis of the τ − → η (′) π − ν τ decays / Garcés, E.A. ; Hernández Villanueva, M. ; López Castro, G. ; Roig, P.
The rare τ − → η (′) π − ν τ decays, which are suppressed by G -parity in the Standard Model (SM), can be sensitive to the effects of new interactions. [...]

2. Five-body leptonic decays of muon and tau leptons / Flores-Tlalpa, A. ; Castro, G. ; Roig, P.
We study the five-body decays μ − → e − e + e − ν μ ν ¯ e $$ {\mu}^{-}\to {e}^{-}{e}^{+}{e}^{-}{\nu}_{\mu }{\overline{\nu}}_e $$ and τ − → ℓ − ℓ ′ + ℓ ′ − ν τ ν ¯ ℓ $$ {\tau}^{-}\to\ {\ell}^{-}{\ell}^{\prime +}{\ell}^{\prime -}{\nu}_{\tau }{\overline{\nu}}_{\ell } $$ for ℓ, ℓ ′ = e, μ within the Standard Model (SM) and in a general effective field theory description of the weak interactions at low energies.

3. Combined analysis of the decays τ − → K S π − ν τ and τ − → K − ην τ / R. Escribano ; S. González-Solís ; M. Jamin ; P. Roig
In a combined study of the decay spectra of τ − − K S π − ν τ and τ − − K − ην τ decays within a dispersive representation of the required form factors, we illustrate how the K * (1410) resonance parameters, defined through the pole position in the complex plane, can be extracted with improved precision as compared to previous studies.

4. Consistent high-energy constraints in the anomalous QCD sector / Roig, Pablo ; Sanz Cillero, Juan José
The anomalous 〈VVP〉 Green function and related form-factors ( π0→γ⁎γ⁎ and τ−→X−ντ vector form-factors, with X−=(KKπ)− , φ−γ , (φV)− ) are analyzed in this letter in the large- NC limit. [...]
