Investigating the correlations of flow harmonics in 2.76A TeV Pb--Pb collisions

Abstract

This proceeding briefly summarizes our recent investigations on the correlations of flow harmonics in 2.76A TeV Pb--Pb collisions with viscous hydrodynamics {\tt VISH2+1}. We calculated both the symmetric cumulants $S{C}^v(m,n)$ and the normalized symmetric cumulants $NS{C}^v(m,n)$, and found $v_2$ and $v_4$, $v_2$ and $v_5$, $v_3$ and $v_5$ are correlated, $v_2$ and $v_3$, $v_3$ and $v_4$ are anti-correlated. We also found $NS{C}^v(3,2)$ are insensitive to the QGP viscosity, which are mainly determined by the initial conditions.
