Description
Heavy quarks are only initially produced in nuclear collisions and the number is conserved during the evolution of the system. We determine the sequence of charmed hadron production by solving a relativistic potential model and hydrodynamic equations. By embedding the charm conservation in a sequential coalescence model, the later produced charmed hadrons are suppressed. Combining together with the strangeness enhancement, the charm conservation effect is significantly enlarged in yield ratios involving charm-strange hadrons like Ds/D0 in heavy ion collisions.
