My name is Jordan Webster. I am a physics Ph.D. student at the University of Chicago. I do High Energy Physics research in the ATLAS collaboration, using particle collision data generated at the Large Hadron Collider in Geneva, Switzerland. I spend most of my time working on a Charge-Parity measurement of the newly discovered Higgs Boson, and helping to develop a Fast Tracker hardware upgrade for the ATLAS detector. In the past, I have worked on searches for exotic vector-like quarks and dark matter.



I have been involved in the following papers/notes:

  • June 2015 - Study of the spin and parity of the Higgs boson in diboson decays with the ATLAS detector [arXiv:1506.05669]
  • Sept 2014 - Fast TracKer (FTK) Performance [CDS]
  • Oct 2013 - Sensitivity to Higgs Tensor Structure in H→ZZ*→4ℓ Decays at the High-Luminosity LHC (internal ATLAS note using Snowmass model) [CDS]
