Measurement of Transverse Momentum Fluctuations in Xe+Xe and Pb+Pb Collisions with ATLAS
Measurements of the first three cumulants of the distribution of the event-by-event transverse momentum distribution, including the mean $\langle[\pT]\rangle$, variance, and skewness, are performed with the ATLAS detector at the Large Hadron Collider. [...]

Studies on the improvement of the matching uncertainty definition in top-quark processes simulated with Powheg+Pythia 8
Top-quark processes, including pair production, single-top production and production in association with electroweak bosons, are modelled by the ATLAS Collaboration by matching the hard-scatter matrix element calculations of next-to-leading order Monte-Carlo generators with a parton shower generator. [...]
