- Description
- The volume of on-shell $D=4$, $\cN=8$ superspace is shown to vanish. Despite this, it is shown that there is a fully supersymmetric and duality-invariant candidate $\nabla^8R^4$ counterterm corresponding to an anticipated seven-loop logarithmic divergence in $D=4$. We construct this counterterm explicitly and also give the complete nonlinear extension of the $1/8$-BPS $\nabla^6R^4$ invariant. Similar results are derived for $\cN=4,5\ \&\ 6$.}
