Simultaneous Dalitz-plot decomposition of the $e^{+} e^{-} \to J / I ¨ I ¨ I ¨ (K K ˉ)$ processes in the 4.13-4.36 GeV region using dispersive final-state interactions

Viktoriia Ermolina, Igor Danilkin, Marc Vanderhaeghen

We present a joint analysis of the processes $e^{+} e^{-} \to J / I ¨ I ¨ ^{+} I ¨ ^{-}$ and $e^{+} e^{-} \to J / I ¨ K^{+} K^{-}$ at center-of-mass energies from 4.13 to 4.36 GeV. The amplitudes are constructed…

Dalitz-plot decomposition for the $e^{+} e^{-} \to J / I ¨ I ¨ I ¨ (K K ˉ)$ and $e^{+} e^{-} \to h_{c} I ¨ I ¨ $ processes

Viktoriia Ermolina, Igor Danilkin, Marc Vanderhaeghen

We present an analysis of the $e^+ e^- \to Î³^* \to J/Ï\, Ï\, Ï\, (K \bar{K})$ and $e^+ e^- \to Î³^* \to h_c \, Ï\, Ï$ processes employing the recently proposed Dalitz-plot de…

Pion polarizabilities from a dispersive analysis of $I^^{3} I^^{3} \to I ¨ I ¨ $

Viktoriia Ermolina, Igor Danilkin, Marc Vanderhaeghen

We present results for the charged and neutral pion polarizabilities, obtained through a dispersive analysis of photon-fusion reactions with two pions in the final state. This anal…
