Medium effects in $\Lambda K^{+}$ pair production by 2.83 GeV protons on nuclei

E. Ya. Paryev, M. Hartmann, Yu. T. Kiselev

We study $\Lambda K^{+}$ pair production in the interaction of protons of 2.83 GeV kinetic energy with C, Cu, Ag, and Au target nuclei in the framework of the nuclear spectral function appr…
