Production rates for hadrons, pentaquarks ${\Theta }^{+}$ and ${\Theta }^{\ast ++}$, and di-baryon $(\Omega \Omega {)}_{0^{+}}$ in relativistic heavy ion collisions by a quark combination model

Feng-lan Shao, Qu-bing Xie, Qun Wang

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 spectr…
