Measurements of differential cross-sections of $W bW b$ production in the dilepton channel in $pp$ collisions at $s$ = 13 TeV using the ATLAS detector

ATLAS Collaboration

At the Large Hadron Collider, the $W bW b$ final state is expected to be dominated by $t t ˉ$ production with a contribution from single-top processes. Differential cross-sections…

Characterization of nuclear breakup as a function of hard-scattering kinematics using dijets measured by ATLAS in $p$ +Pb collisions

ATLAS Collaboration

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…
