Professor Amidei conducts research in particle physics at the CERN LHC and at Fermilab. At the LHC his focus is exploring the implications of the recently observed Higgs boson, which implies either new forces responsible for the Higgs effect or new particles responsible for stabilizing the Higgs interactions. These possibilities can both be explored by finding the Higgs boson in distinctive decay modes and examining its production behavior and associated objects in the event. A speculative combination of both possibilities is resonant Higgs pair production, for which a direct search is under construction. Beyond the Higgs boson, the next LHC run will be the highest energies ever explored and it will be important to look broadly across all indicators for evidence of new phenomena at high mass.
In the DAMIC collaboration at Fermilab, the focus is on a novel technique for the detection of low mass dark matter using extremely sensitive detectors based on the CCD technology originally developed for electronic imaging. An active R&D program with these detectors explores other applications for this extremely sensitive method of radiation detection.
Professor Amidei has previously worked on, and remains interested in, the physics of the top quark, silicon detectors and precision tracking, techniques for b-quark tagging, and electronics for high energy physics. He is a Fellow of the American Physical Society.
