Observing $t\bar{t}Z$ spin correlations at the LHC
Spin correlations between the top quarks in the $t\bar{t}Z$ process are sensitive to new physics. In this phenomenological paper, I predict their values according to the Standard Model, go beyond it with Effective Field Theory, and show that, while a very challenging experimental measurement, there is a case for performing this analysis already with the LHC Run 2 dataset.

The Dark Machines Anomaly Score Challenge: Benchmark Data and Model Independent Event Classification for the Large Hadron Collider
A first outcome of the Dark Machines collider working group! We tried out several hundreds of anomaly detection and density estimation models on simulated datasets of LHC collisions. We now hope to port some of the top-performing models over to actual LHC Run 3 data analyses.
