Prof. Hildreth’s primary physics interest is in discovering and understanding the mechanism or mechanisms responsible for Electroweak Symmetry Breaking. Simply put, this would answer questions like: “why is there mass?” and “is there a Higgs?” As a member of the DØ Experiment at the Tevatron collider at the Fermi National Accelerator Laboratory, Prof. Hildreth is exploring these questions with the large dataset from the Tevatron Run II. He is working on precision measurements of top quark and W boson properties which can be combined with searches for physics beyond the standard model to yield as complete as possible of physics at the highest accessible energies.
While providing greatly enhanced capability, the upgraded DØ detector, especially the scintillating fiber tracker built under Notre Dame supervision, requires a significant effort devoted to understanding the calibration, event reconstruction, the detector simulation, and the impact of all of these on the physics analyses. Prof. Hildreth is involved in all areas of these investigations.
Prof. Hildreth is also a part of the CMS Experiment at CERN’s Large Hadron Collider (LHC) in Geneva, Switzerland, where he will extend the research mentioned above. He is currently leading the CMS group responsible for modeling the interaction of particles with the material of the detector elements. This is essential for understanding the response of the detector to the signals for all of the various physical processes one wishes to study at the collider. The initial years of data taking are a critical time for this work, since the detailed comparison can be made between the modelling and real collider data.
Prof. Hildreth is also involved in an accelerator instrumentation project at SLAC and the KEK laboratory in Tsukuba, Japan. He leads a primarily undergraduate group of students who are building laser interferometer systems to monitor the mechanical stability of accelerator components at the 10 nanometer level. The primary goal of this research is to demonstrate that a precision energy spectrometer based on beam position monitors can attain the necessary resolution.
