These observables directly probe the three- dimensional structure of hadrons, in particular, the quark transversity and Sivers parton distributions and the Collins fragmentation functions. We explore the feasibility of these experimental measurements by detector simulations and discuss detector requirements. We conclude that jet observables have the potential to enhance the three-dimensional imaging EIC program. DOI: 10.1103/PhysRevD.102.074015 I. INTRODUCTION The advent of the electron-ion collider (EIC) [16] with its Jets, collimated sprays of particles, observed in high- high luminosity and polarized beams will unlock the full energy particle collisions, offer a unique opportunity to potential of jets as tools for TMD studies.
