Abstract

The heavy quarks (HQs) are unique probe of the hot QCD matter properties and their dynamics is 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 flavour flow harmonics at LHC energy within a transport approach. Interaction between heavy quarks and light quarks have been taken into account exploring the impact of different temperature dependence of the transport coefficients D_s and Γ. Our study indicates that v^heavy_n-v^light_n correlation and the relative fluctuations of anisotropic flows, σ_v_n/⟨ v_n ⟩, are novel observables to understand the heavy quark-bulk interaction and are sensitive to the temperature dependence even to moderate differences of D_s(T), or Γ(T). Hence a comparison of such new observables for HQ to upcoming experimental data at both RHIC and LHC can put further constraints on heavy quark transport coefficients and in particular on its temperature dependence toward a solid comparison between the phenomenological determination and the lattice QCD calculations.
