Effectivefield theory analysis of the τ − → π − π 0 ν τ decays
/ Miranda, J. ; Roig, P.
We perform an effective field theory analysis of the τ − → π − π 0 ν τ decays, that includes the most general interactions between Standard Model fields up to dimension six, assuming lefthanded neutrinos. [...]

Pseudoscalar pole lightbylight contributions to the muon ( g − 2) in resonance chiral theory
/ Guevara, A. ; Roig, P. ; SanzCillero, J.
We have studied the P → γ ⋆ γ ⋆ transition formfactors ( P = π 0 , η, η ′ ) within a chiral invariant framework that allows us to relate the three formfactors and evaluate the corresponding contributions to the muon anomalous magnetic moment a μ = ( g μ −2) / 2, through pseudoscalar pole contributions.

Effectivefield 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. [...]

Fivebody leptonic decays of muon and tau leptons
/ FloresTlalpa, A. ; Castro, G. ; Roig, P.
We study the fivebody 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.

Combined analysis of the decays τ − → K S π − ν τ and τ − → K − ην τ
/ R. Escribano ; S. GonzálezSolís ; 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.

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