A quark + diquark Faddeev equation treatment of the baryon bound state problem in Poincaré-invariant quantum field theory is used to deliver parameter-free predictions for all six Δ -baryon elastic weak form factors. Amongst the results, it is worth highlighting that there are two distinct classes o...
