Hyperon-production in proton-proton collisions at 4.5 GeV with HADES — •Snehankit Pattnaik¹, Johan Messchendorp¹, and James Ritman^{1, 2} for the HADES collaboration — ¹GSI, Darmstadt, Germany — ²Ruhr-Universität Bochum, Germany

This work presents a preliminary analysis of the Λ + K_S⁰ + p + π⁺ final state in proton-proton scattering using data collected at T = 4.5 GeV with HADES at GSI in Darmstadt, Germany. The production of hyperons is of particular interest since it provides information about the role of N* resonances in strangeness production in NN interactions. Furthermore, this study could be relevant in describing the dynamics of high-density matter such as that located at the core of neutron stars.

This talk will introduce some of the data-driven analysis procedures that have been developed to select the final-state of interest. In particular, a kinematic fitter has been used to efficiently select the signal for this exclusive state. Additionally, the efficiency-corrected Dalitz plot will be discussed.
