Generalized structure functions in semileptonic tau decays

Daniel A. López Aguilar, Antonio Rodríguez Sánchez, Pablo Roig +1

In case there are tensor interactions beyond the SM in the low-energy effective Lagrangian, their interference with the SM V-A currents yields a contribution for tau decays into th…

Effective-field theory analysis of the $τ^{-} \to η^{(')} π^{-} ν_{τ}$ decays

E. A. Garcés, M. Hernández Villanueva, G. López Castro +1

The rare $τ^{-} \to η^{(')} π^{-} ν_{τ}$ decays, which are suppressed by $G$ -parity in the Standard Model (SM), can be sensitive to the effects of new interactions. We study the sen…

A new long distance contribution to $B^{\pm} \to K^{\pm} / π^{\pm} ℓ^{+} ℓ -$ decays

A. Guevara, G. López Castro, P. Roig +1

We have identified a missing long-distance (one-photon exchange) contribution to the $B^{\pm} \to K^{\pm} / π^{\pm} ℓ^{+} ℓ^{-}$ decays. Although it does not help to explain the anomaly mea…

Long-distance weak annihilation contribution to the $B^{\pm} \to (π^{\pm}, K^{\pm}) ℓ^{+} ℓ^{-}$ decays

A. Guevara, G. López Castro, P. Roig +1

We propose an alternative evaluation of the long-distance weak annihilation (WA, also called one-photon exchange in this paper) contribution to the rare semileptonic $B^{\pm}\to (π…

The weak radiative pion vertex in τ^- ->π^-ν_τl^+ l^- decays

P. Roig, A. Guevara, G. López Castro

We carry out a detailed study of the branching fractions and lepton pair invariant-mass spectrum of τ^- ->π^- ν_τl^+l^- decays (l=e,μ). In addition to the model-independent (QED) c…
