Productions of hadrons, pentaquarks Θ+ and Θ*++, and di-baryon (ΩΩ)0+ in relativistic heavy ion collisions by a quark combination model -: art. no. 044903

The hadron production in relativistic heavy ion collisions is well described by the quark combination model. The mixed ratios for various hadrons and the transverse momentum spectra for long-life hadrons are predicted and agree with recent Relativistic Heavy Ion Collider data. The production rates for the pentaquarks Theta(+) and Theta(*++) and the di-baryon (Omega Omega)(0+) are estimated, neglecting the effect from the transition amplitude for constituent quarks to form an exotic state.
