Abstract

We obtain an exact result for the soft-gluon production and its p_T distribution due to a gluon loop in a constant chromoelectric background field E^a with arbitrary color. Unlike Schwinger's result for e⁺e^\ensuremath- pair production in QED which depends only on one gauge invariant quantity, the electric field E, we find that the p_T distribution of the gluons depend on two gauge invariant quantities, E^aE^a and [d_abcE^aE^bE^c]².
