Λ and Σ+ hyperon reconstruction with the upgraded COSY-TOF detector. — •Roman Dzhygadlo1 and Albrecht Gillitzer2 — 1Universität Bonn — 2Forschungszentrum Jülich
New data on hyperon production p→p → KNY (Y=Λ,Σ) at 2.95 GeV/c beam momentum were collected recently with the COSY-TOF detector. Due to the excellent tracking capability, large acceptance and full azimuthal symmetry of the detector setup the quality of the data allows for full and precise reconstruction of Λ and Σ+. Analysis results from these data will cast a light on the structure of nuclear resonances and their coupling to strangeness.
In order to effectively use all tracking information from the detector setup, new track finding and fitting algorithms were developed. Current results of the analysis will be presented and compared to Monte Carlo simulations.
