Michael Kagan (Stanford) "Exploring the TeV Energy Regime with Double Higgs Production at the LHC"
March 17, 2016 @ 4:00 pm - 5:00 pm
The discovery of the Higgs boson by the ATLAS and CMS experiments at the Large Hadron Collider provides a novel tool to search for signs of physics beyond the Standard Model at the LHC. The Higgs boson is central to two frontiers in high energy physics today: the fundamental understanding of the mechanism for Electroweak Symmetry Breaking and for the generation of particle masses, and the exciting prospect of discovering new heavy TeV-scale particles interacting with the Higgs boson. Such new particles are predicted in theories of physics beyond the Standard Model which may incorporate additional symmetries or extra dimensions of space-time. In this talk, I will focus on how the search for di-Higgs boson production using the four bottom quark decay channel is central to probing both of these frontiers. I will discuss the critical developments in bottom quark identification that have enabled such searches for the first time. I will also discuss key advancements in high performance silicon pixel detectors and in new pattern recognition techniques inspired by cutting-edge machine learning and computer vision methods that are extending the future discovery potential at the LHC.
