Azimuthal emission patterns of K+ and of K- mesons in Ni plus Ni collisions near the strangeness production threshold
Azimuthal emission patterns of K+/- mesons have been measured in Ni + Ni collisions with the FOPI spectrometer at a beam kinetic energy of 1.91 A GeV. The transverse momentum p(T) integrated directed and elliptic flow of K+ and K- mesons as well as the centrality dependence of p(T) - differential directed flow of K+ mesons are compared to the predictions of hadron string dynamics and isospin quantum molecular dynamics transport models. The data exhibits different propagation patterns of K+ and K- mesons in the compressed and heated nuclear medium and favor the existence of a kaon-nucleon in-medium potential, repulsive for K+ mesons and attractive for K- mesons.
