Research Interests

  • Research and development of particle detectors
  • Simulation of physics processes and detector response
  • Quantum chromodynamics "jet" reconstruction
  • Search for physics beyond the Standard Model, especially involving the top quark
  • Precision measurements of the top quark.


Professor Rappoccio's research interests are focused on "natural" solutions to the question of why the electroweak scale is different from the Planck scale. The solutions Prof. Rappoccio is most interested in are those where top quarks play a special role in this process, including examinations of models that predict extra spatial dimensions in our universe, and supersymmetry (SUSY).

As a member of the CMS Collaboration, Prof. Rappoccio has been actively involved since 2007. He is involved in QCD jet reconstruction and triggering, advanced techniques for identifying fast-moving heavy particles like top quarks and W/Z/H bosons, and upgrades to the CMS detector in 2013-2015.
