Differential studies of multi-harmonic flow correlations in ALICE — •Anton Riedel for the ALICE collaboration — TU Muenchen, Garching b. M., Deutschland

Symmetric cumulants are a reliable tool for estimating the multi-harmonic correlations between different flow harmonics and have been used in ALICE to constrain the details of η/s temperature dependence of the matter produced in heavy-ion collisions.

In this poster, we present a further differential study of multi-harmonic correlations obtained with symmetric cumulants, SC(k,l) and SC(k,l,m). We present the first results for symmetric cumulants as functions of pseudorapidity η and transverse momentum p_T utilizing Pb–Pb collision at LHC and show how granular the correlations can be extracted using the available statistics. These differential studies provide new and independent constraints both on initial conditions and on the properties of produced nuclear matter.
