Description
Fragmentation functions (FFs), which turn partons into non-perturbative hadronic bound states in hard-scattering reactions, represent a key ingredient to address proton spin structure in semi-inclusive deep inelastic scattering and proton-proton collisions. Fragmentation functions can not be determined from perturbative Quantum Chromodynamics and have to be extracted from experimental data in different processes. The COMPASS experiment at CERN provides a large data sample and covers a wide kinematic range for precise measurement of hadron multiplicities, directly connected to FFs. Recent highly differential results on hadron multiplicity will be presented and discussed for single-hadron and hadron-pair production in SIDIS at COMPASS.
