Description
The modified number of constituent quark (NCQ) scaling
$v_{n}/n_{q}^{n/2} \sim KE_{T}/n_{q}$ for mesons and baryons and the
scaling relation $v_{n} \sim v_{2}^{n/2}$ for higher-order
anisotropic flows, which were observed experimentally, have been
investigated at the top energy of Relativistic Heavy-Ion Collider. It has been found that the modified
NCQ scaling can not be obtained from the naive coalescence even by
taking into account event-by-event fluctuations but may be due to
hadronic afterburner or thermal freeze-out. In addition, we observed
that the behavior of the $v_{n}/v_{2}^{n/2}$ ratio is sensitive to
the partonic interaction. Further insights about the relation between the two scalings are discussed.
