We develop a framework for deriving Dyson-Schwinger Equations (DSEs) andBethe-Salpeter Equation (BSE) in QCD at large $N_c$ limit. The starting pointis a modified form (with auxiliary fields) of QCD generating functional. Thisframework provides a natural order-by-order truncation scheme for DSEs and BSE,and the kernels of the equations up to any order are explicitly given. Chiralsymmetry (at chiral limit) is preserved in any order truncation, so itexemplifies the symmetry preserving truncation scheme. It provides a method tostudy DSEs and BSE beyond the Rainbow-Ladder truncation, and is especiallyuseful to study contributions from non-Abelian dynamics (those arise from gluonself-interactions). We also derive the equation for the quark-ghost scatteringkernel, and discuss the Slavnov-Taylor identity connecting the quark-gluonvertex, the quark propagator and the quark-ghost scattering kernel.
