| description | The heavy quarks (HQs) are a unique probe of the hot QCD matter properties and their dynamics are coupled to the locally thermalized expanding quark gluon plasma. We present here a novel study of the event by event correlations between light and heavy flavor flow harmonics at LHC energy within a transport approach. Interaction between heavy quarks and light quarks have been taken into account to explore the impact of different temperature dependence for transport coefficients Ds and Γ. Our study indicates that vnheavy−vnlight correlation and the relative fluctuations of anisotropic flows, σvn/〈vn〉, are novel observables to understand the heavy quark-bulk interaction and are sensitive to the temperature dependence even to moderate differences of Ds(T), or Γ(T). Hence, the comparison of such new HQ observables to upcoming experimental data at both RHIC and LHC energies can put further constraints on heavy quark transport coefficients and in particular on its temperature dependence toward a solid comparison between phenomenological determination and lattice QCD calculations. |
