Description
This poster presents measurements of the di-jet momentum balance in heavy-ion collisions, focusing on anti-$k_t$ jets with varying radii ($R=$ 0.2, 0.3, 0.4, 0.5, and 0.6) using the ATLAS detector at the LHC. The analysis uses 1.72 $\mathrm{nb}^{-1}$ of Pb+Pb data collected in 2018 and 260 $\mathrm{pb}^{-1}$ of $pp$ data collected in 2017, both at a center-of-mass energy of $\sqrt{s_{\mathrm{NN}}} = 5.02$ TeV. Results are provided for both per-yield and absolute-yield normalizations, with di-jet pair nuclear modification factors reported as functions of the transverse momenta of both leading and sub-leading jets. These measurements reveal insights into how jet energy loss and medium response vary with jet size, contributing to the understanding of parton-medium interactions and jet quenching mechanisms in the quark-gluon plasma.
