Description
Recent efforts at the Large Hadron Collider have opened up new possibilities in studying jet modification and how jets lose energy in different system sizes. From $^{208}Pb$ to $^{16}O$, we observe varying jet energy loss based on the system size. This work presents a modular energy loss treatment (MELT) [1] in the NuclearConfectionery, tuned to central $^{208}Pb$ data. In $PbPb$ collisions, we are able to obtain a reasonable fit to $R_{AA}$ of all charged particles using both a linear and quadratic path-length dependence of energy loss. Using this tuned parameter set we then make predictions for $^{16}O$ and $^{20}Ne$ systems (including nuclear deformation effects in the initial state). We are able to reproduce the $R_{AA}$ in smaller systems and then make predictions for $v_2\{m\}$-$v_4\{m\}$ where $m=2,4$. We also explore new multi-particle cumulant observables with 2+ particles of interest.
