Abstract
We describe a method for introducing gauge fields into nonlocal Lagrangians, and for deriving the resulting Feynman rules. The method is applied in detail to the nonlocal chiral quark model. In particular we describe how to calculate coupling constants of the effective chiral Lagrangian that results when the quarks are integrated out of the theory.Keywords
