Description
Final results on the measurement of charged pion, kaon and unidentified hadron multiplicities in semi-inclusive deep inelastic scattering at the COMPASS experiment at CERN are presented and discussed. Measurements are performed using data collected in 2006 by scattering a 160 GeV muon beam off an isoscalar target, and cover a wide kinematic range defined by Q2 > 1 (GeV/c)2, 0.1 < y < 0.7 and 0.004 < x < 0.7. Results are compared to existing measurements in the overlapping kinematic regions. Collinear fragmentation functions for pions and kaons are extracted from a leading order fit to COMPASS data, these data will also serve as inputs to global QCD fits.
