Description
One of the main goals of the EIC is the understanding of the transverse spin and momentum structure of the nucleon. For such measurements, typically semi-inclusive processes are required where in addition to the scattered lepton kinematics, also at least a final-state hadron is detected. The hadron provides additional flavor sensitivity and the transverse momentum relative to the virtual photon allows to disentangle various contributions such as the quark transversity together with the Collins fragmentation or the Sivers effect. The EIC Yellow report and the subsequent detector proposals have highlighted the physics interest and detector requirements for such TMD measurements. These measurements, the requirements and the anticipated impact of the EIC will be presented.
