Experimental study of the reaction $\hat{I}{ž}^{0}n\to \hat{I}›\hat{I}›X$ using $\hat{I}{ž}^0$-nucleus scattering

BESIII Collaboration, M. Ablikim, M. N. Achasov +703

Using $(10087\pm 44)\times 10^6$$J/\ddot{I}ˆ$ events collected with the BESIII detector operating at the BEPCII storage ring in $2009$, $2012$, $2018$, and $2019$, we perform a search for…
