First measurement of $\Lambda N$ inelastic scattering with $\Lambda$ from $e^{+}{e}^{-}\to J/\psi \to \Lambda \bar{\Lambda }$

BESIII Collaboration, M. Ablikim, M. N. Achasov +636

Using an $e^{+}{e}^{-}$ collision data sample of $(10087\pm 44)\times 10^{6}J/\psi$ events taken at the center-of-mass energy of $3.097\mathrm{GeV}$ by the BESIII detector at the BEPCII colli…
