Dispersive analysis of the $J / ψ \to γ π^{0} π^{0}$ process

Bai-Long Hoid, Igor Danilkin, Anna Testa +1

We present a dispersive amplitude analysis of the low-energy $π^{0} π^{0}$ system in the radiative decay $J / ψ \to γ π^{0} π^{0}$ , using the mass-independent BESIII $0^{++}$ and $2^{++}$ intensi…

Simultaneous Dalitz-plot decomposition of the $e^{+} e^{-} \to J / ψ π π (K K ˉ)$ 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 $e^{+} e^{-} \to J / ψ π^{+} π^{-}$ and $e^{+} e^{-} \to J / ψ K^{+} K^{-}$ at center-of-mass energies from 4.13 to 4.36 GeV. The amplitudes are constructed usin…

Sensitivity of MAGIX@MESA to BSM effects via Bethe-Heitler pair production

Aleksandr Pustyntsev, Marc Vanderhaeghen

We explore the sensitivity of the upcoming MAGIX experiment at the MESA facility to light Beyond the Standard Model (BSM) mediators in the few to hundred MeV mass range. Utilizing…

Subtracted Dispersion Relations for Virtual Compton Scattering off the Proton

I. Danilkin, B. Pasquini, M. Ronchi +1

We present a once-subtracted dispersion relation (DR) formalism for the virtual Compton scattering (VCS) process from threshold up to the $Δ (1232)$ energy region. The formalism aim…

Dispersive analysis of the $ϕ \to γ π^{0} π^{0}$ process

Bai-Long Hoid, Igor Danilkin, Marc Vanderhaeghen

We present an analysis of the radiative decay $ϕ \to γ π^{0} π^{0}$ in a dispersive framework, where the two-pion subsystem undergoes strong final-state interactions that cover the $f_0(…
