abstract
Coalescence of minijet partons with the partons from the quark-gluon plasma formed in relativistic heavy ion collisions is suggested as the mechanism for production of hadrons with intermediate transverse momentum. The resulting enhanced antiproton and pion yields at intermediate transverse momentum gives a plausible explanation for the observed large antiproton to pion ratio. With further increasing momentum, the ratio is predicted to decrease and approach the small value given by independent fragmentations of minijet partons after their energy loss in the quark-gluon plasma.

Including a phenomenological heavy-light quark potential in the coalescence model enhances the heavy-quark coalescence probability to near unity at low momentum without ad hoc normalization.
AMPT generates high elliptic flow with few-millibarn cross sections due to specific features in initial conditions, interactions, and partonic dynamics, identified via comparisons with the MPC model.
The p_T dependence of the Ω/φ ratio in pp, p-Pb and Pb-Pb collisions is dominated by the discrete curvature of the strange-quark transverse-momentum spectrum extracted from φ data via quark-number scaling.
