Abstract: Deep Exclusive Meson Production (DEMP) reactions are an important tool in our quest to better understand the non-perturbative structure of hadrons. They provide one of the clearest pictures of the inner workings of QCD, but the studies are difficult experimentally because of the small reaction cross sections and clean multi-particle coincidence requirements. The Jefferson Lab beam and Hall C detectors are uniquely optimized for these studies, with continuous, high luminosity electron beams, a maximum beam energy of 11 GeV, and detectors capable of precision measurements. In particular: DEMP reactions allow experimental access to the space-like pion elastic form factor and the transition between perturbative and non-perturbative QCD. Similar techniques may allow access to the space-like kaon form factor at high Q2 for the first time. Furthermore, if the hard-soft factorization regime is reached, DEMP reactions allow unique Generalized Parton Distribution data to be acquired. This program is ongoing, the end result of which will be an order of magnitude increase in the world data set for exclusive pion and kaon reactions and form factors.
