10 Introduction Through SDEs, we can study the structure of hadrons
through first principles in the continuum. SDE for QCD have been extensively applied to the study of quark and gluon propagators, their interactions, meson spectra and interactions below the masses ~ 1 GeV. They have been employed to study: The gluon propagator The quark propagator A.C. Aguilar, A.A. Natale, JHEP 08, 057 (2004). A. Ayala, AB, D. Binosi, M, Crisoforetti, J. Rodríguez, Phys. Rev.
