“…The cross section of this channel has been scaled down accordingly. It should be stressed that the adjusted cross sections are consistent with the results of the exclusive analysis of kaon production in the four-body channels p + p → p + π + + Y + K 0 [22].…”

We present the analysis of the inclusive K 0 production in p + p and p + Nb collisions measured with the HADES detector (GSI Helmholtzzentrum for Heavy-Ion Research, Darmstadt) at a beam kinetic energy of 3.5 GeV. Data are compared to the Giessen Boltzmann-Uehling-Uhlenbeck (GiBUU) transport model. The data suggest the presence of a repulsive momentum-dependent kaon potential as predicted by the chiral perturbation theory (ChPT). For the kaon at rest and at normal nuclear density, the ChPT potential amounts to ≈35 MeV. A detailed tuning of the kaon production cross sections implemented in the model has been carried out to reproduce the experimental data measured in p + p collisions. The uncertainties in the parameters of the model were examined with respect to the sensitivity of the experimental results from p + Nb collisions to the in-medium kaon potential.

“…Together with an analysis of the exclusive K 0 production in proton-proton reactions [22], the present data provide a baseline for measurements of strangeness production in nuclear collisions at beam energies of 2-8 GeV/nucleon available at the future Facility for Antiproton and Ion Research (FAIR).…”

“…In view of future experiments at the Facility for Antiproton and Heavy-Ion Research (FAIR) exploring heavy ion collisions at energies of 2-8 GeV/nucleon, new data from proton-proton reactions are essential as reference measurements and input for transport models. This work complements our previous studies of inclusive and exclusive strangeness production in proton-proton reactions at 3.5 GeV, namely K 0 [12], Σ(1385) + [13], Λ(1405) [14,15], and pK + Λ [16]. The paper is organized as follows.…”

We present results on the K * (892) + production in proton-proton collisions at a beam energy of E = 3.5 GeV, which is hitherto the lowest energy at which this mesonic resonance has been observed in nucleon-nucleon reactions. The data are interpreted within a two-channel model that includes the 3-body production of K * (892) + associated with the Λ-or Σ-hyperon. The relative contributions of both channels are estimated. Besides the total cross section σ(p + p → K * (892) + + X) = 9.5 ± 0.9 +1.1 −0.9 ± 0.7 µb, that adds a new data point to the excitation function of the K * (892) + production in the region of low excess energy, transverse momenta and angular spectra are extracted and compared with the predictions of the two-channel model. The spin characteristics of K * (892) + are discussed as well in terms of the spin-alignment.

“…The best environment to carry out this kind of studies is provided by hadron-hadron collisions at few GeV kinetic energies because at these energies large baryonic densities, similar to those within NS, can be created. On the other hand the reaction dynamics at these energies is dominated by hadronic resonances, that need then to be quantitatively understood [6][7][8][9][10][11][12][13]. For final states containing pions and nucleons produced in elementary reactions, partial wave analysis (PWA) was already employed to correctly take into account interferences among resonances and determine the amplitude of the contributing waves [14][15][16][17].…”
