abstract = {We determine the flavour dependence of the renormalisation-group-invariant running interaction through judicious use of both
unquenched Dyson-Schwinger equation and lattice results for QCD’s gauge-sector two-point functions. An important step is the
introduction of a physical scale setting procedure that enables a realistic expression of the e ect of di erent numbers of active quark
flavours on the interaction. Using this running interaction in concert with a well constrained class of dressed–gluon-quark vertices,
we estimate the critical number of active lighter-quarks above which dynamical chiral symmetry breaking becomes impossible:
