Description
Rapidity dependence of directed flow ($v_1$) and elliptic flow ($v_2$) were analyzed for various particles, including proton, deuteron, triton, $\mathrm{^{3}He}$, and $\mathrm{^{4}He}$ observed in collisions involving $\mathrm{^{132}Sn+{}^{124}Sn}$ and $\mathrm{^{108}Sn+{}^{112}Sn}$ collisions at 270 $\mathrm{MeV/u}$.
The flow was larger for heavier charged particles, i.e.,
the slope of $v_{1}$ ($v_{11}$) and the negative $v_2$ at the mid-rapidity ($v_{20}$) were enhanced for the heavier charged particles.
To understand the experimental data, we compared them with AMD calculations which explicitly consider the cluster correlation.
Two types of momentum-dependent mean field potential were utilized.
AMD calculations explain the increasing flow trend for the heavier particles, but a close comparison shows that the mass dependence is stronger in experimental data.
The sensitivity to the density dependence of the symmetry energy and
the system dependence is also examined.
