Strangeness Production Process $pp\to n{K}^{+}{\Sigma }^{+}$ within Resonance Model

Xu Cao, Xi-Guo Lee, Qing-Wu Wang

We explore production mechanism and final state interaction in the $pp\to n{K}^{+}{\Sigma }^{+}$ channel based on the inconsistent experimental data published respectively by COSY-11 and COS…
