Physics and Astronomy
One of the top 10 unsolved problems in physics is the nature of the strong force where quark confinement dominates. i.e. it is poorly understood how quark and gluon interactions give rise to the observed properties of mesons and nucleons. This has motivated an ambitious program in Deep Exclusive electron scattering reactions, where the system responds coherently to the incoming probe and provides a clearer picture of the inner workings of QCD (the theory of strong interactions in the Standard Model). I will describe several upcoming experiments at the newly upgraded Jefferson Lab (USA), which will take data with unprecedented accuracy and will measure some of these properties for the first time to better understand the underlying quark-gluon structure of these particles.
