Abstract
Employing the Bonn-Gatchina partial wave analysis framework (PWA), we have analyzed HADES data of the reaction p(3.5GeV)+p→pK+Λ. This reaction might contain information about the kaonic cluster "ppK−" via its decay into pΛ. Due to interference effects in our coherent description of the data, a hypothetical K¯¯¯NN (or, specifically "ppK−") cluster signal must not necessarily show up as a pronounced feature (e.g. a peak) in an invariant mass spectra like pΛ. Our PWA analysis includes a variety of resonant and non-resonant intermediate states and delivers a good description of our data (various angular distributions and two-hadron invariant mass spectra) without a contribution of a K¯¯¯NN cluster. At a confidence level of CLs=95\% such a cluster can not contribute more than 2-12\% to the total cross section with a pK+Λ final state, which translates into a production cross-section between 0.7 μb and 4.2 μb, respectively. The range of the upper limit depends on the assumed cluster mass, width and production process.
