      abstract     = {This Letter analyzes the sensitivity of event geometry
                      estimators to the initial-state kinematics of hard
                      scattering in proton-lead collisions. This analysis uses
                      dijets as a proxy for the parton-parton scattering
                      configuration, correlating it with event geometry
                      estimators, namely the energy deposited in the Zero-Degree
                      Calorimeter and the transverse energy recorded in the
                      Forward Calorimeter in the Pb-going direction. The analysis
                      uses data recorded by the ATLAS detector at the Large Hadron
                      Collider with a nucleon-nucleon center-of-mass energy of
                      8.16 TeV, corresponding to an integrated luminosity of 56
                      nb$^{-1}$. The jets are measured within the pseudorapidity
                      interval $-$2.8 $<$$\eta$$<$ 4.5, where positive $\eta$
                      values correspond to the direction of the proton beam.
                      Results are presented as a function of the Bjorken-$x$ of
                      the parton originating from the proton, $x_{p}$. Both event
                      geometry estimators are found to be dependent on $x_{p}$,
                      with the energy deposited in the Zero-Degree Calorimeter
                      about six times less sensitive to $x_{p}$ compared with the
                      transverse energy deposited in the Forward Calorimeter.},
