Role of $K_0^{\ast }(700)$ exchange in the $p\bar{p}\to \hat{I}›\bar{\hat{I}}›$ reaction

Hao-Nan Wang, Cheng Chen, Xing-Yi Ji +4

The paper uses an effective Lagrangian model to study the antiproton‑proton → Λ Λ̄ reaction, showing that t‑channel exchange of the scalar meson K*_0(700) together with s‑channel v…
