“…On the other hand, π-nucleus reactions at beam energies of 1.65 GeV showed that the same φ/K − ratio is obtained when comparing π − + C and π − + W reactions [17]. Since a strong difference in the absorption of K − is observed in the two targets, the constant φ/K − ratio speaks for a strong φ absorption as well.…”

“…The main motivation for this kind of studies is that, in HICs at intermediate energies (kinetic energies of few GeV maximally), baryonic densities up top 2 − 3 ρ 0 should be reached and, hence, the kinematic of the produced hyperons might be modified by the hyperon rescattering within the dense medium. Such measurements have been carried out for p + p/A [301,302], π − + A [17,138] and A + A [142] collisions at intermediate energies to study elementary reactions as a reference, light colliding systems to test the properties of hyperons at saturation densities, and finally HICs to infer on the hyperon propagation within dense environments. So far, the only way to investigate possible in-medium modifications of hyperons is the comparison to transport models, where the interaction can be varied.…”

“…In order to quantify the in-medium effects in an alternative way, the rapidity and momentum distribution of K 0 S or/and K + have been analyzed by several experiments: KaoS [140], FOPI [138] and HADES [17,134] at GSI.…”

“…The left panel of Fig. 13 shows the rapidity distributions of K + and K − produced in π − + C and π − + W reactions with an incident beam momentum of 1.65 GeV/c measured by the HADES spectrometer at GSI [17]. One can see that the K + rapidity distributions differ strongly between the two targets, and that for the heavier target the kaons are predominantly emitted in the backward direction (the arrow represents the center of mass rapidity of the πN system).…”

“…The φ, in particular, is very narrow in vacuum and is well separated from the ρ and the ω mesons, allowing for the measurement of any modifications of its mass or width in matter. To that end, several experiments have been carried out, such for photoproduction [13,14], for proton-induced [15,16] and pion-induced [17] reactions, an effort that has been accompanied by important theoretical developments to understand the modifications of the φ meson in dense nuclear matter.…”

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 aim of the AMADEUS collaboration is to provide experimental information on the low-energy strong interaction of antikaons with nucleons, exploiting the absorptions of low momentum K − mesons ( p K ∼ 127 MeV/c) produced at the DA NE collider, in the materials composing the KLOE detector setup, used as an active target. The K − single and multi-nucleon absorptions in light nuclei ( 4 He and 12 C) are investigated by reconstructing hyperon-pion, hyperon-nucleon/nucleus pairs, emitted in the final state of the reactions. In this paper the results obtained from the study of π − , p and t correlated production are presented.
