Abstract
Recent analysis of Large Hadron Collider (LHC) Run 1 data has shown an apparent mismodelling is Higgs pT from ATLAS γγ and 4ℓ decay channels, as well as the CMS 4ℓ decay channel.This has been referred to as the pT crisis, and it is postulated that it can be explained by the Higgs being produced in combination with a dark matter particle. A minimal Z' is modelled as a dark matter mediator and shown to have cross sections too low to satisfy current experimental constraints. The viability of a two-Higgs-doublet model providing a form of dark matter is then argued to be a viable solution to an excess of double Higgs production events from Run 1 LHC data, and an experimental analysis done by ATLAS is given as motivation. I conclude by noting that these analyses will be enhanced by data from Run 2 of the LHC.
