“…This result is indeed compatible with the calculations using the free space total cross section of the π − + p → Λ + K 0 reaction, which provide an average total kaon production cross section of <K> = 71 µb for central Au + Au collisions at 2 AGeV. Note that the inclusion of even a slight modification of the K + mass because of the nuclear medium (without the corresponding changes introduced here) leads to a substantial reduction of the inclusive K + spectra (by as much as a factor of 2 or 3), compared to that calculated using the free space properties for the relevant hadrons [8].…”

Abstract. Results for the π + N → Λ, Σ + K reactions in nuclear matter of Ref.[1] are presented. To evaluate the in-medium modification of the reaction amplitude as a function of the baryonic density we introduce relativistic, meanfield potentials for the initial, final and intermediate mesonic and baryonic states in the resonance model. These vector and scalar potentials were calculated using the quark meson coupling model. Contrary to earlier work which has not allowed for the change of the cross section in medium, we find that the data for kaon production at SIS energies are consistent with a repulsive K + -nucleus potential.

“…For the energies considered, microscopic transport models are usually employed and have a history of succesfully describing experimental observables. Several previous works found that the production rates and properties of Kaons, for example are a promising probe to extract their medium interactions in low energy nuclear collisions [3,4,5,6,7,8,9,10,11,12,13,14,15].…”

Abstract. We present recent results on the sub-threshold production of strange and charmed hadrons in nuclear collisions. In particular we highlight how the excitation and decay of heavy baryonic resonances can be used to describe the production yield of φ mesons at the SIS18 accelerator and show how this production mechanism also consistently describes the φ nuclear transparency ratio. Including even more massive baryonic resonances in the model we are able to extend our approach and make, for the first time, realistic predictions on the sub-threshold production of J/Ψ and Λc in nuclear collisions at the SIS100 accelerator at FAIR. We find that even at a beam energy of E lab = 6 A GeV, charm physics is feasible at the CBM experiment, which opens up new opportunities to study charmed hadron properties at large baryon densities.

“…From the analysis of the out-of-plane [28,29] and sideward flow [19,30], the K + -nucleon potential is deduced to be mildly repulsive, and the measured K + production yields are in agreement with the scenario of a soft nuclear equation of state (incompressibility modulus K N ≈ 200 MeV) [31,32]. The interpretation of the K − data is still undergoing systematic evaluations to pin down the value of the presumed attractive K − -nucleon potential and its momentum dependence.…”
