Nuclear Physics Seminar
"New Studies of Elastic Nucleon Form Factors"
Presented by Dr. Seamus Riordan, Stony Brook University
Tuesday, April 7, 2015, 11:00 am — Small Seminar Room, Bldg. 510
The electromagnetic form factors of the nucleon provide experimental access to the underlying charge and magnetic moment distributions arranged by the strong nuclear force. These form factors provide excellent testing grounds for QCD and QCD-inspired models and are fundamentally important in understanding non-perturbative strong force physics. By studying them over a broad range of momentum transfers, they provide insight into the underlying mechanisms relevant to the generation of nucleon structure. At low Q2 there is presently a controversy regarding the charge radius measurements of the proton. At high Q2, scaling of the form factors are presently being studied in the context of a transition from soft QCD interactions. In this talk I will provide an overview of our present experimental of elastic nucleon form factors, review their context within current theoretical models, discuss upcoming future measurements at Jefferson Lab, in particular the Super Bigbite program.
