Re-using old measurements to set new constraints on composite dark matter

New paper out on the arXiv today, with Jonathan Butterworth, Suchita Kulkarni, and some talented UCL MSci students.

“Dark Sector” models, in which a bunch of new particles (some of which could explain Dark Matter = DM) are connected to the particles we know about (the Standard Model = SM) only via their interaction with e.g. the Higgs boson, can look radically different depending on what parameters you choose. So far, the approach taken to test these models have been a piecemeal set of searches for specific realisations of the model, which is not very efficient given how much these can vary.

Instead, we used our CONTUR tool to automatically confront these models to the bank of 100s of LHC measurements to date, yielding stringent new constraints, and we use existing lattice calculations to propagate them to limits on Dark Matter mass. Model-independent measurements of differential cross-sections can be re-used again and again, which makes this a more efficient way to rule out parts of the Dark Sector parameter space.
