Description
We present results on the improvement coefficient of the non-singlet axial-vector current, with particular emphasis on imposing improvement conditions in the chiral limit and at the flavour-symmetric point.
For its determination, the established Ward-identity method is employed in $N_{\rm f}=3$ QCD with stabilised Wilson-Clover fermions.
We simulate with Schrödinger functional boundary conditions and box-sizes of about $3\,{\rm fm}$ for $a \in [0.120, 0.055]\,{\rm fm}$.
Furthermore, we report on our plans to extend such calculations to access other improvement coefficients and renormalisation factors.
