Tuning of the helix string model on the DELPHI $Z^0\rightarrow q\bar{q}$ data
An alternative model of the fragmentation of the Lund string, investigating the hypothesis of helix-like ordered gluon field, is compared with hadronic $Z^0$ data. A significant improvement in the description of various measured quantities is achieved. In particular, the existence of correlations between longitudinal and transverse components of hadron momenta (as suggested by the helix string model) seems to be supported by the data.
