High Energy Physicists study and seek to discover the fundamental particles and interactions upon which our universe is built.  The Notre Dame HEP Group is actively engaged in a major experiment in Europe called CMS, that is rapidly advancing our knowledge of this physics, at the Large Hadron Collider at the CERN Laboratory in Geneva, Switzerland.

This presentation focuses on how we detect particles and interactions.   A hand-held particle detector, developed at Notre Dame, is brought into the discussion that shows three of the fundamental elements of matter: electrons, photons and muons right in the lecture hall.  This type of detector, built by students and teachers, has been placed in high energy particle beams to reveal visually the interactions of particles with matter.   It is impressive to see what high energy particles can do…!
