Dark matter could have its origin in a new, strongly coupled, dark sector with fermion constituents that form dark analogies to the standard model mesons. These dark mesons could have been produced in the 13 TeV proton-proton collisions in the LHC Run 2.

In this seminar, I describe my ongoing search for Dark Mesons in Run 2 data collected with the ATLAS detector. I show preliminary results that suggest that we will be sensitive to a large part of the parameter space of the model. I also present an unsupervised clustering algorithm for particle physics data, and how its training can be distributed over arbitrarily many machines, making the model fully scalable. Lastly, I will discuss studies made on using the fast simulation tool Extrapolation Engine for prospect studies in the effort for a new hardware track trigger for the ATLAS experiment.
