Investigating the Correlations of Flow Harmonics in 2.76A TeV Pb–Pb Collisions

This proceeding briefly summarizes our recent investigations on the correlations of flow harmonics in 2.76A TeV Pb-Pb collisions with viscous hydrodynamics VISH2+1. We calculated both the symmetric cumulants SCv (m, n) and the normalized symmetric cumulants NSCv (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 NSCv (3, 2) are insensitive to the QGP viscosity, which are mainly determined by the initial conditions.
