    "abstract": "The quark Dyson-Schwinger equation and meson Bethe-Salpeter equation are\nstudied in a truncation scheme that extends the rainbow-ladder approximation\nsuch that, in the chiral limit, the isovector, pseudoscalar meson remains\nmassless. Quark-quark (diquark) correlations, which are bound in rainbow-ladder\napproximation, are destabilised by repulsive contributions that only appear at\nhigher order in the Bethe-Salpeter kernel. The net effect of higher order terms\non the meson bound-state masses is small.",
