Measurement of the quark and gluon fragmentation functions in Z $^0$ hadronic decays
1999
European Physical Journal C: Particles and Fields
The transverse, longitudinal and asymmetric components of the fragmentation function are measured from the inclusive c harged particles produced in e + e collisions at LEP. As in deep inelastic scattering, these data are important for tests of QCD. The transverse T and longitudinal L components of the total hadronic cross section tot are evaluated from the measured fragmentation functions. They are found to be T = tot = 0 : 949 0:001(stat:) 0:007(syst:) and L = tot = 0 : 051 0:001(stat:)
