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 SCv(m,n)SC^{v}(m, n) and the normalized symmetric cumulants NSCv(m,n)NSC^{v}(m, n), and found v2v_{2} and v4v_{4}, v2v_{2} and v5v_{5}, v3v_{3} and v5v_{5} are correlated, v2v_{2} and v3v_{3}, v3v_{3} and v4v_{4} are anti-correlated. We also found NSCv(3,2)NSC^{v}(3, 2) are insensitive to the QGP viscosity, which are mainly determined by the initial conditions.Comment: SQM2016 proceeding, 4pages, 2 figure
