Title: Measurement of the $ω \to π^{0} e^{+} e^{-}$ and $η \to e^{+} e^{-} γ$ Dalitz decays with the A2 setup at the Mainz Microtron

Abstract

The Dalitz decays η → e⁺e^-γ and ω → π⁰e⁺e^- have been measured in the γp → ηp and γp → ωp reactions, respectively, with the A2 tagged-photon facility at the Mainz Microtron. The value obtained for the slope parameter of the electromagnetic transition form factor of η, Λ$$-2\atop{η}$$ = (1.97 ± 0.11_tot) GeV^-2, is in good agreement with previous measurements of the η → e⁺e^-γ and η → μ⁺μ^-γ decays. The uncertainty obtained in the value of Λ$$-2\atop{η}$$ is lower than in previous results based on the η → e⁺e^-γ decay. The value obtained for the ω slope parameter, Λ$$-2\atop{ωπ^0}$$ = (1.99 ± 0.21_tot) GeV^-2, is somewhat lower than previous measurements based on ω → π⁰μ⁺μ^-, but the results for the ω transition form factor are in better agreement with theoretical calculations, compared to earlier experiments.

Measurement of the $π^{0} \to e^{+} e^{-} γ$ Dalitz decay at the Mainz Microtron

Journal Article Adlarson, P. ; Afzal, F. ; Aguar-Bartolomé, P. ; ... - Physical Review C

The Dalitz decay π⁰ → e⁺e^-γ has been measured in the γp → π⁰p reaction with the A2 tagged-photon facility at the Mainz Microtron, MAMI. The value obtained for the slope parameter of the π⁰ electromagnetic transition form factor, a_π= 0.030 ± 0.010_tot, is in agreement with existing measurements of this decay and with recent theoretical calculations. The uncertainty obtained in the value of a_π is lower than in previous results based on the π⁰ → e⁺e^-γ decay.

High-statistics measurement of the $η \to 3 π^{0}$ decay at the Mainz Microtron

Journal Article Prakhov, S. ; Abt, S. ; Achenbach, P. ; ... - Physical Review. C

Here, the largest, at the moment, statistics of 7 × 10⁶ η → 3π⁰ decays, based on 6.2 × 10⁷ η mesons produced in the γp → ηp reaction, has been accumulated by the A2 Collaboration at the Mainz Microtron, MAMI. It allowed a detailed study of the η → 3π⁰ dynamics beyond its conventional parametrization with just the quadratic slope parameter α and enabled, for the first time, a mea- surement of the second-order term and a better understanding of the cusp structure in the neutral decay. The present data are also compared to recent theoretical calculations that predictmore »« less

Experimental study of the $γ p \to π^{0} η p$ reaction with the A2 setup at the Mainz Microtron

Journal Article Sokhoyan, V. ; Prakhov, S. ; Fix, A. ; ... - Physical Review C

Here, the data available from the A2 Collaboration at MAMI were analyzed to select the γp → π⁰ηp reaction on an event-by-event basis, which allows for partial-wave analyses of three-body final states to obtain more reliable results, compared to fits to measured distributions. These data provide the world’s best statistical accuracy in the energy range from threshold to E_γ = 1.45 GeV, allowing a finer energy binning in the measurement of all observables needed for understanding the reaction dynamics. The results obtained for the measured observables are compared to existing models, and the impact from the new data is checkedmore »« less
