Fast hadronization of charm, bottom and strange flavor in strangeness rich QGP

ORAL

Abstract

We study QGP hadronization at a given $b$ bottom, $c$ charm and $s$ strange quark content conserving entropy. We evaluate the final yields of charm and bottom flavored hadrons within statistical hadronization model. In fast hadronization at fixed reaction volume the high strangeness $s$ and entropy $S$ content of QGP leads to chemical non-equilibrium condition among final state charm and bottom hadrons. We predict a significant increase of their yield, compared a slow (chemical equilibrium) hadronization. Yields of hadrons with two heavy quarks, including $J/\Psi$, decrease compared to expectations since charm (bottom) is `used up' in strange hadron formation. This provides a new powerful mechanism of $J/\Psi$ and $\Upsilon$ suppression. The yield of light hadrons without strangeness depends mainly on the temperature $T$ of hadronization and the related light quark fugacity $\gamma_q$. However the ratio of non-strange to strange hadrons always decreases with increasing of $s/S$.
