Abstract: | We show that high-p⊥RAA and v2 are sensitive to the early expansion dynamics, and that the high-p⊥ observables prefer delayed onset of energy loss and transverse expansion. To calculate high-p⊥RAA and v2, we employ our newly developed DREENA-A framework, which combines state-of-the-art dynamical energy loss model with (3+1)-dimensional hydrodynamical simulations. The model applies to both light and heavy flavor, and we predict a larger sensitivity of heavy flavor observables to the onset of transverse expansion. This presents the first time when bulk QGP behavior has been constrained by high-p⊥ observables and related theory, i.e., by so-called QGP tomography. |
