Abstract
In this work we present a strong chiral meson Lagrangian up to and including in the momentum expansion. It is derived from the Nambu--Jona-Lasinio (NJL) model using the heat-kernel method. Identities related to the properties of covariant derivatives of the chiral matrix as well as field transformations have been used to obtain a minimal set of linearly independent terms.
