Xiaohui Liu, Felix Ringer, Werner Vogelsang, and Feng Yuan, Lepton-Jet Correlations in Deep Inelastic Scattering at the Electron-Ion Collider, Phys. Rev. Lett. 122, 192003 (2019)

The high energy and high luminosity Electron-Ion Collider (EIC) is regarded as the next generation QCD machine which is aimed at exploring the structure of nucleons and nuclei. In this work we proposed the measurement of jets (collimated sprays of particles) at the EIC which constitute unique tools to study various interesting physics aspects. We focused specifically on electron-jet correlations studies in deep inelastic scattering processes. Jets can be used to explore the (transverse) spin structure of the proton and they constitute sensitive probes of cold nuclear matter effects such as transverse momentum broadening. In general, we expect that jet physics will set a new direction of the EIC science program. Our studies are presented in a timely manner such that they can be taken into account in the planning phase of the EIC.
