Seth Zenz is an expert on the Higgs boson who became a Lecturer in the QMUL Particle Physics Research Centre in 2018. He completed his PhD in 2011 at the University of California, Berkeley on the ATLAS experiment, studying the properties of jets in early LHC data. Over the course of two postdocs at Princeton University and Imperial College London, he made a range of measurements within the Higgs program at the Compact Muon Solenoid collaboration and led its Higgs to di-photon analysis group for 2016-18.
Motivated by the central role of charged particle tracking in all Higgs boson measurements, he has made contributions to the construction and operation of the silicon pixel detectors for both ATLAS and CMS. He now works on the ITk Upgrade for the ATLAS detector in preparation for the High Luminosity LHC; see PPRC Research Facilities for more details.
Seth makes precise measurements of the Higgs boson in order to identify new interactions not predicted by the Standard Model of particle physics. This can take the form of Simplified Template Cross Section or other "binned" cross section measurements, or extraction of parameters in the context of particular models. His current focus is on Higgs decays to bottom quarks in association with a vector boson. He is keen to explore all of the "ingredients" that go into such measurements, including:
- Jet structure and substructure
- Novel machine learning algorithms
- Improved statistical combination
He also works on the ATLAS Inner Tracker upgrade and developing new tracker technology (and new tracking algorithm approaches) for future colliders.
