Description
We here present two frameworks that allow generating a wide range of predictions from the dynamical energy loss formalism [1,2]. In distinction to majority of other methods, the dynamical energy loss formalism takes into account a realistic medium composed of dynamical scattering centers. The first framework (DREENA-C) [1] applies to the medium with constant temperature, while the second framework applies to evolving medium modeled by Bjorken 1+1D expansion (DREENA-B) [2]. We here present joint $R_{AA}$ and $v_2$ predictions for light and heavy flavor, for different systems, centralities and collision energies. DREENA-C (constant temperature) predictions overestimate $v_2$. For DREENA-B (Bjorken expansion) we obtain a good agreement with both $R_{AA}$ and $v_2$ data. Introducing medium evolution has a larger effect on $v_2$, but for precision predictions it also has to be taken into account for $R_{AA}$. These results argue the dynamical energy loss formalism can provide a basis for a state of the art QGP tomography tool.
