Description
Semi-inclusive deep-inelastic scattering (SIDIS) provides a powerful tool to explore the multidimensional structure of the nucleon and the dynamics of hadronization. Measurements of hadron multiplicities and spin-dependent asymmetries offer complementary sensitivity to transverse-momentum-dependent parton distributions and fragmentation functions. This talk will present an overview of recent experimental studies of SIDIS, with emphasis on results from Jefferson Lab, together with complementary measurements from other SIDIS experiments such as COMPASS. Selected measurements of charged- and neutral-hadron multiplicities and spin asymmetries will be discussed, highlighting their multidimensional kinematic dependences and their sensitivity to nucleon structure and fragmentation. Recent experimental and analysis developments, as well as ongoing efforts toward increasingly precise multidimensional SIDIS measurements, will also be highlighted.
