Extracting Kinetic Freeze-Out Properties in High-Energy Collisions Using a Multisource Thermal Model

The invariant yields, , of (a) , , and , as well as (b) , , and produced in in Au–Au collisions with different centrality percentages at  GeV. The symbols represent the experimental data measured by the STAR Collaboration [45]. The curves are our results fitted by the single-component function (or the first component in the three-component function), where the sum of contributions of two (for mesons) or three (for baryons) contributor partons is considered.
