SCIENCE GOALS

Precision Measurements of Pion and Kaon Form Factors and Structure Functions.

Form factors are the most basic quantity towards understanding light hadron structure. The structure functions in terms of sea quarks and gluons are expected to be different for pions, kaons, and nucleons and to provide basic information about their origin of mass.

Validation of understanding of hard exclusive and semi-inclusive reactions towards 3D hadron imaging and potential future flavor decomposition.

The key to this validation is precision longitudinal-transverse separated data.
