Description
Directed and elliptic flow have been extensively studied in heavy-ion collisions while triangular flow ($v_3$) could be further explored. $v_3$ could prove very useful as a signal for Quark-Gluon Plasma (QGP) formation due to its link to viscosity and the possibility that it is less affected by transport dynamics at very low energies [1]. This poster presents the current progress of an analysis on $v_3$ for $\pi$, $K$, $p$, $d$, and $t$ at the fixed target energies of $\sqrt{s_{NN}}=3.0$ GeV and $7.2$ GeV from phase-II of the Beam Energy Scan at STAR. The results include a correlation between $v_3$ and the first-order event plane and a clear rapidity-odd $v_3$ for $p$. This is the first in a series of collision energies at STAR below and above the QGP phase transition where triangular flow for identified particles will be studied.
