Exploring Jet Quenching Through the Measurement of the Dijet Momentum Balance with ATLAS

High energy partons are known to lose energy when passing through the hot and dense medium produced in heavy-ion collisions. This results in a modification to the transverse momentum distributions of jets. It has been previously shown in Pb+Pb collisions at 2.76 TeV that parton energy loss within th...

description High energy partons are known to lose energy when passing through the hot and dense medium produced in heavy-ion collisions. This results in a modification to the transverse momentum distributions of jets. It has been previously shown in Pb+Pb collisions at 2.76 TeV that parton energy loss within the Quark Gluon Plasma results in significant modifications to the transverse momentum balance of dijet pairs. However, additional differential measurements are needed to better understand the path-length dependence as well as the role of medium fluctuations to the energy loss. This poster presents the latest measurements of fully unfolded dijet momentum balance in Pb+Pb and $pp$ collisions at 5.02 TeV. Additionally, the dijet momentum balance in Pb+Pb collisions is measured with respect to the second order azimuthal event plane angle, providing further insight on the path-length dependence to energy loss.
