Description
Quark fragmentation functions (FF) $D^h_q(z,Q^2)$ describe final-state hadronisation of quarks $q$ into hadrons $h$.
The FFs can be extracted from hadron multiplicities produced in semi-inclusive deep inelastic scattering. The COMPASS collaboration has recently measured charged hadron multiplicities for identified pions and kaons using a 160\,GeV/c muon beam impinging on an isoscalar LiD target. The data cover a large kinematical range and provide an important input for global QCD analyses of world data at NLO, aiming at the determination of FFs. The newest results from COMPASS on pion multiplicities and pion fragmentation functions will be discussed.
