Effect of $K^{*}$ meson magnetic dipole moment on the $e^{+} e^{-} \to K^{+} K^{-} π^{0} π^{0}$ cross section

Luis A. Jiménez Pérez, Antonio Rojas, Genaro Toledo

We explore the sensitivity of the $e^{+} e^{-} \to K^{+} K^{-} 2 π^{0}$ cross section to the magnetic dipole moment (MDM) of the $K^{*}$ vector meson. We describe the $γ^{*} \to 2 K 2 π$ vertex…

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…
