The Tagged Deep Inelastic Scattering experiment at JLab

The Tagged Deep Inelastic Scattering (TDIS) experiment in Hall A at the Jefferson Laboratory is an ambitious experiment making use of a new multiple time projection chamber in conjunction with the Super Bigbite Spectrometer (SBS) to study the internal structure of hadrons. The experiment was originally designed to measure the structure functions (SFs) of pions through the Sullivan process (electron scattering off of the nucleon meson cloud), making use of the tagging technique (measuring one or more of the recoil nucleons in coincidence with the scattered electron). Two run groups have been added to the original proposal. First is the novel measurement of the kaon SF, and the second is a comprehensive measurement of the neutron SFs in the valence and resonance regions, the neutron magnetic form factor, and the Deuterium EMC effect.

This talk will present the motivation and the current status of the experiment.
