Revisiting the deuteron mass radius via near-threshold $\ddot{I}{}^0$, $\ddot{I}‰$ and $\ddot{I}•$ meson photoproduction

Xiaoxuan Lin, Wei Kou, Shixin Fu +3

We present a comprehensive analysis of near-threshold photoproduction of $\ddot{I}{}^0$, $\ddot{I}‰$, and $\ddot{I}•$ mesons on a deuterium target, utilizing published datasets from DESY and SLAC for $Ï…
