Description
As a hadronization model in relativistic heavy-ion collisions, coalescence (recombination) model has achieved great success in the description of the production of hadron and light nuclei. This talk focuses on light-nuclei production within the framework of the coalescence model. By employing the characteristic function of the phase space density, we derive the yield of light nuclei in terms of various orders of cumulants for the density distribution function. We found that the leading terms of the phase-space cumulants in the yield nuclei share a similar form and could be canceled out in light-nuclei ratio, whereas the higher order ones (non-Gaussian shaped density profile) remain and play an important role in the interpretation of the behavior of light nuclei yield ratio. In addition, the critical correlation contributed to the higher-order phase-space cumulants will also be discussed.
