“…Three issues were mainly investigated thereby: the production of N * resonances and their subsequent decay into K + Λ [2][3][4][5][6][7][8][9][10], the pΛ final state interaction [7,[11][12][13], and the cusp structure appearing at 2.13 GeV in the pΛ invariant mass distribution [14][15][16]. A fourth aspect was recently added to this list with the investigation of the kaonic nuclear bound state KN N by the DISTO collaboration [17,18].…”

Our answer to the question posed in the title is: probably no. In this work we show that it is rather unlikely that the structure X(2265) reported by the DISTO collaboration corresponds to a kaonic nuclear bound state. The main argumentation is based on the repetition of the DISTO analysis on the HADES data sample, containing p+p reactions at 3.5 GeV. We further discuss many aspects in connection with the pK + Λ final state and the Λ(1405)-resonance. The results evidence possible problematics in the interpretation of the DISTO data.

The Λp interaction close to the ΣN threshold is considered. Specifically, the pronounced structure seen in production reactions like K − d → π − Λp and pp → K + Λp around the ΣN threshold is analyzed. Modern interaction models of the coupled ΛN −ΣN systems generate such a structure either due to the presence of a (deuteron-like) unstable bound state or of an inelastic virtual state. A determination of the position of the prominent peak as observed in various experiments for the two aforementioned reactions leads to values that agree quite well with each other. Furthermore, the deduced mean value of 2128.7 ± 0.3 MeV for the peak position coincides practically with the threshold energy of the Σ + n channel. This supports the interpretation of the structure as a genuine cusp, signaling an inelastic virtual state in the 3 S1 − 3 D1 partial wave of the ΣN isospin 1/2 channel. There is also evidence for a second peak (or shoulder) in the data sets considered which appears at roughly 10-15 MeV above the ΣN 1 threshold. However, its concrete position varies significantly from data set to data set and, thus, a theoretical interpretation is difficult.
