Beyond scalar QED radiative corrections: the $ρ^{\pm} - ρ^{0}$ width difference, FSR corrections and their impact on $Δ a_{μ}^{HVP, LO} [τ]$

F. V. Flores-Baez, G. López Castro, Genaro Toledo

In a previous paper arXiv:0708.3256 [hep-ph] we have calculated the radiative corrections to $ρ \to π π$ decays, aiming to estimate the width difference between charged and neutral r…

Semileptonic $D_{e 4}$ decays: hadronic dynamics and the determination of $∣ V_{cs} ∣$

J. L. Gutiérrez Santiago, G. López Castro

The four-body decays $D^{+} \to K^{-} π^{+} e^{+} ν_{e}$ ( $D_{e 4}^{+}$ ) and $D^{0} \to K^{0} π^{-} e^{+} ν_{e}$ ( $D_{e 4}^{0}$ ) are studied in a model where the momentum-dependence of the hadronic matr…
