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

We determine the qqBAR pair creation probability in the color flux tub e model including effects of non-Abelian interactions in the theory. I t is suggested that the color field should be time dependent due to no n-Abelian interactions and hence should oscillate with a characteristi c collective frequency omega0, which depends on the field strength. Ou r results show that in p-p and A-A collisions, either the perturbative estimate (omega0 much greater than m) or multigluon ionization (omega 0 much less than m) process often gives the dominant contribution to t he creation of qqBAR pairs
