The Proton Radius - Old Measurements and New Ideas (Prof. G. Ron)

  • Date: Dec 4, 2015
  • Time: 14:00 - 16:00
  • Speaker: Prof. Dr. Guy Ron, Hebrew University of Jerusalem and George Washington University
  • Room: Herbert Walther Lecture Hall
  • Host: MPQ, Laser Spectroscopy Division
The radius of the proton, generally assumed to be a well measured and understood  quantity has recently come under scrutiny due to highly precise, yet conflicting, experimental results. These new results have generated a host of interpretations, none of which are completely satisfactory.

I will discuss the existing results, focusing on the discrepancy between the various extractions. I will briefly discuss some theoretical attempts at resolution and focus on new scattering measurements, both planned and already underway, that are attempting to resolve the puzzle.
