    "abstract": "The relativistic transport model, in which the nucleon effective mass is\nconnected to the scalar field while its energy is shifted by the vector\npotential, is extended to include the kaon degree of freedom. We further take\ninto account the medium modification of the kaon mass due to the explicit\nchiral symmetry breaking. Both the propagation of kaons in the mean-field\npotential and the kaon-baryon elastic scattering are explicitly treated in our\nstudy. We find that the attractive kaon scalar mean-field potential in the\ndense matter leads to an enhanced kaon yield in heavy-ion collisions at\nenergies of about 1 GeV/nucleon. The final-state kaon-baryon scattering is seen\nto affect significantly the kaon momentum spectra, leading to an enhanced yield\nof kaons with large momenta or at large laboratory angles. With a soft nuclear\nequation of state and including the attractive kaon scalar potential, the\ncalculated kaon energy spectra agree with the data from the heavy-ion\nsynchrotron at GSI.",
