【 摘 要 】

We discuss the investigation of the strange meson production in proton-proton (𝑝𝑝) and proton–nucleus (𝑝𝐴) reactions within an effective Lagrangian model. The kaon production proceeds mainly via excitations of 𝑁* (1650), 𝑁* (1710), and 𝑁* (1720) resonant intermediate nucleonic states, in the collision of two initial state nucleons. Therefore, the strangeness production is expected to provide information about the resonances lying at higher excitation energies. For beam energies very close to the kaon production threshold the hyperon–proton final state interaction effects are quite important. Thus, these studies provide a check on the models of hyperon–nucleon interactions. The in medium production of kaons shows strong sensitivity to the self-energies of the intermediate mesons.
