Strange and nonstrange hadron resonance production by quark coalescence, investigating quark number scaling

Research output: Contribution to journalArticle


RHIC data on light and strange hadron resonance production induced an extended discussion on hadron production mechanisms in heavy ion collisions. Resonance yields are far from the thermal expectations and standard coalescence models have also difficulties to reproduce these yields. We have developed the Resonance Coalescence Model (RCM) which contains the features of coalescence and quark scaling, and includes the width of the hadron resonances. It opens a way to handle resonances in the high mass region for all non-strange, strange and charm hadron resonances within the same description scheme. The talk focuses on the model structure, the question of quark scaling with resonances and predictions for strange and charm resonance ratios.
