Universal four-dimensional hadron jets and the observability of colour charges

A new definition of the jets as clusters in the four-velocity space has been used to make an invariant analysis of the jet production processes in ν-barN collisions for the three energy intervals of the hadron system: =3.5; 4.9; 8.0 GeV. The obtained results are compared with the characteristics of the four-dimensional jets in various types of interactions: pp, p-barp, π-p, π-C, pC and pTa at energies from 6 to 205 GeV. The characteristics of the four-dimensional jets in soft and hard interactions are shown to be universal, i.e. independent of neither the type of the fragmenting system (p, p-bar, π-, C, q) nor the collision energy for Plab ≥ 22 GeV/c ((Sq root)S=W > 6 GeV). The obtained result means that the hadronization of the colour charges is determined by the dynamics of their interaction with vacuum
