The Next Steps in Particle Physics: Using the Higgs Boson to Discover the Unknown
The start of the Large Hadron Collider (LHC) nearly a decade ago opened a new era of fundamental physics. The discovery of the Higgs boson in 2012 completed the Standard Model of particle physics. Despite the enormous success of the Standard Model, there are still open questions, including the particle nature of dark matter. The recent discovery of the Higgs boson has opened a new way to address this question. In particular, it is possible that the Higgs boson could mediate the interactions between dark matter and the Standard Model and subsequently decay to invisible particles. I will begin with a discussion of constraints from Higgs boson property measurements. The main focus of my talk is how to search for evidence of invisible decays of the Higgs boson using the ATLAS detector. Since the LHC plans to continue to take data for another 20 years, I will discuss the long term physics goals as well as experimental challenges.
