Triangular flow of charged particles in heavy ion collisions from the STAR experiment at RHIC, Y. Pandit, Kent State University, USA − The study of azimuthal anisotropy, characterized by Fourier coefficients, is widely recognized as an important tool to probe the hot, dense matter created in heavy ion collisions. The third harmonic flow, v3, also called triangular flow, can shed light on the initial geometry and its fluctuations, and on the hydrodynamic expansion of the medium.
We present measurements of triangular
charged particles from Au + Au collisions at sqrt(sNN)
= 200 GeV
recorded with the STAR detector at RHIC. Triangular flow as a
centrality and transverse momentum are reported using various
including a study of the signal for particle pairs as a function
pseudorapidity separation; analyses of this type can help
different sources of non flow correlations. Results are also compared
with available hydrodynamical
and transport models.
