Description
Target fragmentation provides a unique window into the correlation between the struck parton and the remnant system in semi-inclusive deep-inelastic scattering. While current and past studies of nucleon structure have largely focused on current fragmentation observables, the Electron-Ion Collider will enable precision measurements in the target-fragmentation region through its high luminosity, wide kinematic reach, and dedicated forward detection capabilities. These measurements can access fracture functions, which describe the probability of finding the parton in the target while observing a specific hadron produced directly from the target remnant.
In this talk, we discuss key fracture-function observables at the EIC, including leading baryon production, identified hadrons at large rapidity, transverse-momentum correlations, and flavor- and spin-dependent target-fragmentation channels.
