“…MeV were associated to the resulting deviation spectrum. This interpretation was however strongly criticized [103], since the deviation spectrum normalized to a phase-space simulation does not take into account the contributions of baryonic resonances decaying into the K + Λ final state. Indeed, detailed partial-wave analyses of the same reaction p + p → p + K + + Λ at kinetic energies between 2 and 4.5 GeV [96,104] demonstrated the contribution of N * resonances with masses between 1650 and 1950 MeV and the role played by interferences among these resonances.…”

We review the present status of the experimental and theoretical developments in the field of strangeness in nuclei and neutron stars. We start by discussing theKN interaction, that is governed by the presence of the Λ(1405). We continue by showing the two-pole nature of the Λ(1405), and the production mechanisms in photon-, pion-, kaon-induced reactions as well as proton-proton collisions, while discussing the formation ofKN N bound states. We then move to the theoretical and experimental analysis of the properties of kaons and antikaons in dense nuclear matter, paying a special attention to kaonic atoms and the analysis of strangeness creation and propagation in nuclear collisions. Next, we examine the φ meson and the advances in photoproduction, protoninduced and pion-induced reactions, so as to understand its properties in dense matter. Finally, we address the dynamics of hyperons with nucleons and nuclear matter, and the connection to the phases of dense matter with strangeness in the interior of neutron stars.

“…The possible existence of compact K − pp clusters was proposed by Yamazaki and Akaishi [11] and has attracted a lot of attention experimentally and theoretically. Following first claims of observing kaonic clusters [12,13] conflicting results have been reported and the existence of such states discussed controversially (see recent publications [14][15][16] and references cited therein). The binding energy of these states may not be very large and they may have a rather large width which makes it difficult to detect them experimentally.…”

The experiment has been performed with the combined Crystal Barrel and MiniTAPS detector system, using tagged photon beams from the ELSA electron accelerator. Information on the sign and magnitude of the real part of the η ′ -Nb potential has been extracted from a comparison of the data with model calculations. An attractive potential of −(41 ± 10(stat) ± 15(syst)) MeV depth at normal nuclear matter density is deduced within model uncertainties. This value is consistent with the potential depth of −(37 ± 10(stat) ± 10(syst)) MeV obtained in an earlier measurement for a light nucleus (carbon). This relatively shallow η ′ -nucleus potential will make the search for η ′ -nucleus bound states more difficult.

“…Therefore, it is very important to understand the reaction dynamics of the Λ * p →"K − pp" process. The incident energy dependence observed in the p + p → K + Λp reactions with two groups, DISTO (2.5 GeV and 2.85 GeV) and HADES (3.5 GeV), might be a useful input for such theoretical studies [24,25].…”
