TRANSPORT MODEL STUDY OF IN-MEDIUM KAON POTENTIAL IN HEAVY ION COLLISIONS
Keywords:
Kaon production, heavy ion collisions, the in-medium kaon potential, transport studyAbstract
The kaon production in heavy ion collisions at intermediate energies provides a sensitive probe to study the in-medium properties of hadrons. Properties of kaons in dense hadronic matter are important for a better understanding of both a possible restoration of chiral symmetry in dense hadronic matter and the properties of nuclear matter at high densities. It is known from chiral models that the kaon mean field is related to chiral symmetry breaking. The K+ and K- mean field potentials play a crucial role. In the lowest order approximation to the chiral Lagrangian, the kaon (antikaon)potential has an attractive scalar and a repulsive (attractive) vector part. Experimental and transport model studies on the in-medium potential of kaon produced in heavy ion collisions at intermediate energies are reviewed.
