- A high statistics measurement of the p̅p → pK⁺Λ reaction was done with the COSY-TOF experiment. The proton beam was polarized up to more than 80%, and its momentum was 2.95 GeV/c. The reconstruction of the pK⁺Λ events was done only with the straw tube tracker due to the higher spatial resolution of the straw tube tracker compared to other subdetectors. The Dalitz plot of the pK⁺Λ events was analyzed to understand the reaction mechanism and presented in this paper. The Dalitz plot shows that the COSY-TOF experiment provides complete kinematic coverage of the phase space of this reaction which made it ideal for p̅p → pK⁺Λ reaction analysis. The influence of different physical effects as pΛ final state interaction, excited nucleon states (N*-resonances) and a coupled channel effect of NΣ-pΛ (NΣ cusp effect) produce significant structures in the Dalitz plot. The angular distribution of the particles in the CMS and helicity frame was also presented in this paper.
