Description

The discovery of the Higgs boson at the LHC has opened up the possibility for new physics to be discovered through its couplings and decays. In particular, it could serve as a portal to dark sectors by coupling to invisible particles or even dark matter. We consider 2 models where an interesting characteristic signature is that of di-Higgs production in association with missing energy. We introduce simplified models with a possible UV completion and study the limits we can place on these models by virtue of its couplings to the Higgs boson for a range of benchmark scenarios. We consider the dominant, $b\bar b$ decay channel of both Higgs bosons. The corresponding complex final state and large backgrounds motivates us to make use of multivariate analysis techniques to optimise our results.
