Schwinger effect for non-Abelian gauge bosons

Understand

We investigate the Schwinger effect for the gauge bosons in an unbroken non-Abelian gauge theory (e.g.

• the gluons of QCD).
• We consider both constant "color electric" fields and "color magnetic" fields as backgrounds.
• As in the Abelian Schwinger effect we find there is production of "gluons" for the color electric field, but no particle production for the color magnetic field case.
