    "abstract": "The hadron production in relativistic heavy ion collisions is well described\nby the quark combination model. The mixed ratios for various hadrons and the\ntransverse momentum spectra for long-life hadrons are predicted and agree with\nrecent RHIC data. The production rates for the pentaquarks $\\Theta ^+$, $\\Theta\n^{*++}$ and the di-baryon $(\\Omega\\Omega)_{0^{+}}$ are estimated, neglecting\nthe effect from the transition amplitude for constituent quarks to form an\nexotic state.",
