Reconstruction of the pp → nK⁺Σ⁺ reaction at COSY-TOF — •Pawel Klaja — Erlangen-Nuremberg University

The COSY-TOF detector setup was upgraded with a new tracking system. A high statistics measurement with this setup in August 2010 was dedicated to hyperon production with a polarized proton beam of 2.95 GeV/c momentum. The main goal of this measurement was to measure the spin triplet pΛ scattering length, the spin transfer coefficient of the pp → pK⁺Λ reaction and the investigation of N^* resonances.
In addition the pp → nK⁺Σ⁺ reaction is examined at an excess energy of Q = 128.7 MeV.
The current status of the data analysis in view of pp → nK⁺Σ⁺ reaction identification will be presented. The procedure of data selection as well as the reconstruction method will be discussed.
