About the event

The Department of Physics and Astronomy invites all to a colloquium featuring Dr. Gerald Miller, Department of Physics, University of Washington. Dr. Miller will present their talk, “Proton Radius Puzzle – Why We All Should Care”

Meet for refreshments before the lecture at 3:45 – 4:10 p.m. in the foyer on floor G above the lecture hall.


Electronic and muonic probes have separately been used to measure the radius of the proton, but  significantly different results have been obtained with each probe. This difference has been denoted the proton radius puzzle. Understanding this problem requires knowledge of atomic, nuclear, hadronic and particle physics.  The main interest in this subject is the intriguing possibility that violations of electron-muon universality exist. Recent experiments and the various possible solutions, will be reviewed.
