Description
We present an update on the determination of renormalization constants and improvement coefficients for exponential-clover improved Wilson fermions in the coupling regime of interest for the large volume simulations of the OpenLat initiative ($a\approx 0.034-0.12\,{\rm fm}$). Particular focus is put on the renormalization of the non-singlet vector current using a massless renormalization scheme to determine the renormalization constant $Z_{\rm V}$ and its massive improvement coefficients $b_{\rm V}$ and $\bar{b}_{\rm V}$. Furthermore, we present an update on the improvement coefficient $c_{\rm A}$ and results on the renormalization of the non-singlet axial-vector current, $Z_{\rm A}$.
