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…

The $ρ$ meson magnetic dipole moment from BaBar $e^{+} e^{-} \to π^{+} π^{-} π^{0} π^{0}$ cross section measurement

Antonio Rojas, Genaro Toledo

We obtain the value of the magnetic dipole moment of the $ρ$ meson, using data from the BaBar Collaboration for the $e^{+} e^{-} \to π^{+} π^{-} 2 π^{0}$ process. The considered center o…

Sizing the double pole resonant enhancement in $e^{+} e^{-} \to π^{0} π^{0} γ$ cross section and $τ^{-} \to π^{-} π^{0} ν_{τ} γ$ decay

Leonardo Esparza-Arellano, Antonio Rojas, Genaro Toledo

The enhancement mechanism due to the resonant properties of the $ρ$ and $ω$ mesons, which are close in mass, are analysed when such resonances carry different momenta. Consideratio…

Model independent analysis of femtoscopic correlation functions: An application to the $D_{s 0}^{*} (2317)$

Natsumi Ikeno, Genaro Toledo, Eulogio Oset

We face the inverse problem of obtaining the interaction between coupled channels from the correlation functions of these channels. We apply the method to the interaction of the $D…

Resonant Majorana neutrino effects in $Δ$ L=2 four-body hyperon decays

Gerardo Hernández-Tomé, Diego Portillo-Sánchez, Genaro Toledo

We computed the $Σ^{-} \to n π^{+} e^{-} ℓ^{-}$ ( $ℓ = e, μ$ ), $Ξ^{-} \to Λ π^{+} e^{-} e^{-}$ , and $Λ \to p π^{+} e^{-} e^{-}$ lepton number violating (LNV) hyperon decays mediated by a resonant Majorana neutr…

Taming the long distance effects in the $D_{s}^{+} \to π^{+} ℓ^{-} ℓ^{+}$ decay

Marxil Sánchez, Genaro Toledo, I. Heredia De La Cruz

The semileptonic decay $D_{s}^{+} \to π^{+} ℓ^{-} ℓ^{+}$ , where $ℓ = e, μ$ , is used as a reference channel when looking for suppressed or forbidden processes of the s…

Interpretation of the $Ω_{c} \to π^{+} Ω (2012) \to π^{+} (K ˉ Ξ)$ relative to $Ω_{c} \to π^{+} K ˉ Ξ$ from the $Ω (2012)$ molecular perspective

Natsumi Ikeno, Wei-Hong Liang, Genaro Toledo +1

We present a mechanism for $Ω_{c} \to π^{+} Ω (2012)$ production through an external emission Cabibbo favored weak decay mode, where the $Ω (2012)$ is dynamically generated from the inte…

Unveiling the $K_{1} (1270)$ double-pole structure in the $B ˉ \to J / ψ ρ K ˉ$ and $B ˉ \to J / ψ K ˉ^{*} π$ decays

J. M. Dias, G. Toledo, L. Roca +1

By looking at the pseudoscalar-vector meson spectra in the $B ˉ \to J / ψ ρ K ˉ$ and $B ˉ \to J / ψ K ˉ^{*} π$ weak decays, we theoretically investigate the double-pole structu…

Theoretical study of the $D^{0} \to K^{-} π^{+} η$ reaction

Genaro Toledo, Natsumi Ikeno, Eulogio Oset

We develop a model to study the $D^{0} \to K^{-} π^{+} η$ weak decay, starting with the color favored external emission and Cabibbo favored mode at the quark level. A less favored intern…

Searching for a $D D ˉ$ bound state with the $ψ (3770) \to γ D^{0} D ˉ^{0}$ decay

Lianrong Dai, Genaro Toledo, Eulogio Oset

We perform a calculation of the mass distribution in the $ψ (3770) \to γ D D ˉ$ decay, studying both the $D^{+} D^{-}$ and $D^{0} D ˉ^{0}$ decays. The electromagnetic interaction is…

Molecular picture for the $Ω (2012)$ revisited

Natsumi Ikeno, Genaro Toledo, Eulogio Oset

We conduct a study of the interaction of the $K ˉ Ξ^{*}$ , $η Ω$ ( $s$ -wave) and $K ˉ Ξ$ ( $d$ -wave) channels within a coupled channel unitary approach where the transition potential…

$R_{D^{*}}$ or $R_{D π}$ : closing the theoretical gap?

J. E. Chavez-Saab, Marxil Sánchez, Genaro Toledo

Measurements of the $R_{D^{*}}$ parameter remain in tension with the standard model prediction, despite recent results helping to close the gap. In this work, we revisit the standard…

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

Javier Rendón, Pablo Roig, Genaro Toledo

We analyze the $τ^{-} \to (K π)^{-} ν_{τ}$ decays within an effective field theory description of heavy new physics (NP) modifying the SM left-handed weak charged current and include refined…
