Title:     The Proton Electromagnetic Form Factor Ratio at Low Q^2

Abstract: Electromagnetic form factors of the nucleon are model-independent observables which encode our ignorance of its complex internal structure. In recent years significant attention has been drawn to these observables due to the discovery of unexplained deviations from previously measured results. Recoil polarization measurements are allowing the electric to magnetic form factor ratios be determined with unprecedented precision. New results from MIT-BLAST and, more recently, from Hall A at Jefferson Lab indicate that there is an unexpected decrease in the proton form factor ratio at low Q^2 . Even newer data is expected to come from MAINZ and JLab experiments in the near future. This talk will discuss the nucleon form factors, specifically in the low Q^2 region, previous and new measurements, and the potential impacts of these results.

Stimulants available 15 minutes before the talk.
