2. Energy loss of partons propagating through medium studied for three different models • Simulation based on relativistic fluid dynamics, identical evolution and properties used for each of three models used

3. Models • Higher twist (HT)‏ • medium-enhanced higher twist corrections to the total cross section in deep inelastic scattering • ˆq - energy-density • Arnold-Moore-Yaffet (AMY)‏ • energy loss of hard jets is considered in an extended medium in equilibrium at T →∞ • ˆq - temperature • Armesto-Salgado-Wiedemann (ASW)‏ • ˆq – entropy-density • incoming and outgoing partons multiple scattering effects in terms of a path integral over a path-ordered Wilson line

4. RAA as a function of the transverse momentum and centrality of collision, as well as the angle with respect to the reaction plane
