Partial wave contributions to the antikaon potential at finite momentum Original Research Article

The momentum dependence of the antikaon optical potential in nuclear matter is obtained from a microscopic and self-consistent calculation using the meson-exchange Jülich View the MathML source interaction. Two self-consistent schemes are discussed, which would lead to substantially different predictions for the width of View the MathML source nuclear bound states. The effect of higher partial waves of the View the MathML source interaction, beyond the L=0 component, is studied and found to have moderate but nonnegligible effects on the View the MathML source nuclear potential at zero momentum. At momenta as large as 500 MeV/c, relevant in the analysis of heavy-ion collisions, the higher partial partial waves modify the View the MathML source optical potential by nearly a factor of two.
