ResumoAt low momentum transfer the QCD strong-coupling constant is large, and the expectations based on the strong coupling expansion (in low orders) may provide a valid guide to the strong interaction physics of nuclei. I employ the strong coupling expansion (SCQCD) and argue that quark exchange effects (without interaction) are absent or suppressed. Furthermore flux-tube rearrangements seem small, and QCD string breaking effects resemble meson emission from hadrons. Thus SCQCD seems to reproduce the qualitative features of the meson-baryon picture of low momentum transfer conventional nuclear physics.
