High $p_{\mathrm{T}}$ spectra and anisotropy of light and heavy hadrons

Abstract

Data driven studies of heavy-ion results has played a big role in highlighting interesting features of these complex systems. In this proceeding, a simple QGP-brick interpretation of the $R_{\mathrm{AA}}$ and $v_2$ at high $p_{\mathrm{T}}$ ($p_{\mathrm{T}}\approx 10$ GeV/c) is presented. This interpretation draws attention to two fundamental questions: is there an effect of the asymmetric QGP expansion on the $v_2$ at high $p_{\mathrm{T}}$? is there an energy loss difference between quarks and gluons? Finally, it is discussed how these studies can be extended using Event-Shape Engineering and how they can be applied to compare the energy loss of light and heavy quarks.
