Description
Schwinger pair production is examined in SU(2) (SL(2,C)) background fields through the worldline instanton method, whose non-Abelian equivalent stems from Wong’s equations. The role of group complexification for pair production in non-Abelian fields is elucidated. The gauge group winding number is compared and contrasted with the worldline instanton winding number, related to number of produced pairs, for special topologically non-trivial background gauge configurations.
