Abstract

Abstract: Recent analysis of Large Hadron Collider (LHC) Run 1 data has shown an apparent mismodelling is Higgs pT from ATLAS γγ and 4 ℓ decay channels, as well as the CMS 4 ℓ 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.
