Professor Judah M. Eisenberg Memorial Lecture "The Proton Radius Puzzle -Why We All Should Care?"
Professor Gerald Miller, Department of Physics, University of Washington, Seattle, USA
Professor Gerald Miller is a Guest Lecturer at the Emilio Segre Distinguished Lectures in Physics Endowed by Raymond and Beverly Sackler for the academic year 2017/2018
Electron and muon probes have separately been used to measure the radius of the proton, but different results have been obtained. This difference has been denoted the proton radius puzzle. The main interest in this subject is the intriguing possibility that violations of electron-muon universality exist. The various possible solutions, which involve experimental, atomic, nuclear and particle physics, will be reviewed.
