On the transverse momentum distribution of strange hadrons produced in relativistic heavy ion collisions

  • Short Note
  • Published:
Zeitschrift für Physik A Hadrons and Nuclei

Abstract

Particles with strange quark content produced in the system 1.93A·GeV58Ni on58Ni have been investigated at GSI Darmstadt with the FOPI detector system. The correlation of these produced particles was analyzed with respect to the reaction plane.Λ baryons exhibit a very pronounced sideward flow pattern which is qualitatively similar to the proton flow. However, the kaon (K +,K 0s ) flow patterns are significantly different from that of the protons, and their form may be useful to restrict theoretical models on the form of the kaon potential in the nuclear medium.
