Abstract
In the present paper, physical arguments are given in favour of measuring the fragmentation functions D{sub q}{sup -h}(z,s) in the process e{sup +}e{sup -}{yields}h+X(h-{pi}, K, p is an identified hadron, X stands for all others) at LEP energies. It is shown that due to the QCD prediction of strong scaling violation in the region of time-like momentum transfers q (q{sup 2}>0, the channel of the lepton-antilepton annihilation into the hadrons, q{sup 2}=S), that is essentially more strong than the analogous effect in the space-like region (q{sup 2}<0, the deep-inelastic lepton-hadron scattering channel, - q{sup 2}=Q{sup 2}>0), the study of these fragmentation functions is of great interest. The measurement of the forward-backward asymmetry for hadrons produced in the reaction e{sup +}e{sup -}{yields}h+X will make it possible to determine the W{sub 3}(z,s) structure function that contains the contribution of the neutral quark currents leading to the parity-violation effects. 35 refs.; 8 figs.; 1 tab.
