Nuclear Physics Projects at Jefferson Lab

When compared to our precise knowledge of electricity and magnetism (via
quantum electrodynamics), the fundamental nature of matter at the quark and
gluon level of subatomic physics is still only partially understood.
This week's colloquium features the efforts of the ISU subatomic physics
research group to improve this understanding of the strong force by using
photon and electron probes at Jefferson Lab in Newport News, Virginia.
Dr. Dan Dale will describe his experiment to measure the neutral pion lifetime
via the Primakoff effect. This is a very precise test of Quantum Chromo
Dynamics, the theory of the strong force. Dr. Phil Cole will outline
a research program using polarized photons to explore the excited states
of the nucleon. Using polarization sheds light on how quarks are bound
within the substructure of protons. This further gives insight into
the nature of the strong force. Dr. Tony Forest will describe his research
into the quark contributions to nucleon observables using polarized electron
probes and polarized nucleon targets. A key component to the research
program will be the development of an ionization-based detector system for
tracking relativistic charged particles in the upgrade to Hall B at Jefferson
Lab. There will be plenty of research opportunities for ISU students.
The physics motivations of the program and the roles available to graduate
will be the main focus of this talk.
