TL;DR

This paper reports measurements of the third harmonic flow coefficient, $v_3$, in Au+Au collisions at 200 GeV, providing insights into the azimuthal anisotropy of charged particles and comparing results with models and other experiments.

Contribution

First measurement of the third harmonic flow coefficient $v_3$ in Au+Au collisions at 200 GeV using multiple analysis methods.

Findings

$v_3$ varies with centrality, pseudorapidity, and transverse momentum.

Results are consistent with certain theoretical models.

Comparison with other experiments validates the measurement techniques.

Abstract

In this proceedings, we report measurements of the third harmonic coefficient of the azimuthal anisotropy, $v_{3}$, known as triangular flow. The analysis is for charged particles near midrapidity in Au+Au collisions at $\sqrt {s_{NN}} $ = 200 GeV, based on data from the STAR experiment at the Relativistic Heavy Ion Collider. Triangular flow as a function of centrality, pseudorapidity and transverse momentum are reported using various methods, including a study of the signal for particle pairs as a function of their pseudorapidity separation. Results are compared with other experiments and model predictions.
