Q(Q)OVER-BAR PAIR PRODUCTION IN NON-ABELIAN GAUGE-FIELDS

We determine the qqBAR pair creation probability in the color flux tube model including effects of non-Abelian interactions in the theory. It is suggested that the color field should be time dependent due to non-Abelian interactions and hence should oscillate with a characteristic collective frequency omega0, which depends on the field strength. Our results show that in p-p and A-A collisions, either the perturbative estimate (omega0 much greater than m) or multigluon ionization (omega0 much less than m) process often gives the dominant contribution to the creation of qqBAR pairs
