    "abstract": "Antikaon production from heavy ion collisions at energies available from the\nAlternating Gradient Synchrotron (AGS) at the Brookhaven National Laboratory is\nstudied in a relativistic transport (ART) model. We include contributions from\nthe baryon-baryon, meson-baryon, and meson-meson interactions. The final-state\ninteraction of antikaons via both absorption and elastic scattering by nucleons\nand pions are also considered. To compare with presently available or future\nexperimental data, we have calculated the antikaon rapidity and transverse\nmomentum distributions as well as its collective flow. Medium effects on these\nobservables due to mean field potentials have also been investigated. It is\nfound that the ratio of antikaon transverse momentum spectrum to that of kaon\nand their transverse flow are most sensitive to the in-medium properties of\nkaons and antikaons.",
