Event Plane Correlated Triangular Flow in Au+Au Collisions at √s_NN = 3 GeV from STAR

Directed and elliptic flow have been extensively studied in heavy-ion collisions while triangular flow (v₃) could be further explored. v₃ could prove very useful as a signal for Quark-Gluon Plasma (QGP) formation due to its sensitivity to QGP viscosity and the possibility that it is less affected by transport dynamics at very low energies [1]. This talk presents the current progress of an analysis on v₃ for π, p, d, and t at the fixed target energy of √s_NN = 3.0 GeV, which is the lowest in phase-II of the Beam Energy Scan at STAR. The results show a positive correlation between v₃ and the first-order event plane and a significant rapidity-odd v₃ for p. In the future, these triangular flow measurements will be studied at other collision energies in STAR.
