First study of reaction ${\Xi }^{0}n\to {\Xi }^{-}p$ using ${\Xi }^0$-nucleus scattering at an electron-positron collider

BESIII Collaboration, M. Ablikim, M. N. Achasov +604

Using $(1.0087\pm 0.0044)\times 10^{10}$ $J/\psi$ events collected with the BESIII detector at the BEPCII storage ring, the process ${\Xi }^{0}n\to {\Xi }^{-}p$ is studied, where the ${\Xi }^0$…
