Investigation of the Λ(1405) production in p+p→p+K+Λ(1405) reaction

In this paper، the invariant mass spectra of Λ (1405) → (Σπ) 0 in high energy proton-proton collisions in center of mass frame have been theoretically investigated. In pp collision the Λ (1405) formation possibility has been taken into account and its decay rate to (Σπ) 0 channel، has been calculated with T-matrix elements and Green’s function method. Finally، the results have been compared with the ANKE data for the first time، and using X2 method the confidence level diagrams have been obtained. The X2 fitting shows a good agreement between experimental data and the ones obtained in current paper.
