Description
The kaon production in heavy ion collisions at intermediate energies provides a sensitive probe to study the in-medium properties and nuclear equation of state. Kaon properties in dense hadronic matter are important for understanding of nuclear matter at high densities. We investigated the in-medium kaon potential by rapidity density distribution and transverse mass spectra for ${K^ + }$mesons in heavy ion collisions. We used Quantum Molecular Dynamics Model (QMD model) based on covariant kaon dynamics to simulate ${}_{13}^{27}Al + {}_{13}^{27}Al$ collisions at beam energy 1.9 A GeV. Calculated results with a repulsive in-medium ${K^ + }N$ potential can reasonably describe the features of FOPI experiment data. They also shown that the transverse mass spectrum of ${K^ + }$ mesons is a sensitive observable to probe the kaon in-medium potential in dense nuclear matter.
