Speaker
Description
This talk will discuss upcoming tagged deep inelastic scattering (TDIS) measurements in Hall A of Jefferson Lab, which will probe the elusive mesonic content of the nucleon. The TDIS experiment will measure low momentum recoiling (and spectator) hadrons in coincidence with deep inelastically scattered electrons from hydrogen (and deuterium) targets. The recently installed Hall A Super Bigbite Spectrometer, a large acceptance detector package, will be used to detect the electrons. For the hadron detection, a novel, high-rate capable, multiple time projection chamber (mTPC) is being developed. Through use of the mTPC, a tagging technique will enhance deep inelastic scattering from partons in the meson cloud and provide access to the pion and kaon structure functions in the valence regime. An overview of the measurement program will be given.
