Julie Roche, Ohio University, Title of Talk: Tomography of the proton
The proton is a composite particle made up of quark and gluon. The details of how gluons and quarks are confined within the proton remain surprisingly mysterious. For example, the elegant theory that governs the interaction of gluons and quarks, Quantum ChromoDynamics (QCD), cannot be solved analytically at the proton size scale. Experimentally, while the spatial distribution and the momentum distribution of quarks and gluons inside the proton are known, the correlation between the two is not. Generalized Parton Distributions (GPDs) were introduced in 1995. They encode this correlation. In this talk, I will review the worldwide data of this emerging field of study. I will also emphasize the importance of the precision experimental approach implemented by my JLAB collaboration.
