Description
The quark-chrom EDM (qCEDM) is a dimension 5 operator parametrizing at low energy BSM contributions to a non-vanishing EDM.
We discuss the implementation of the qCEDM with the gradient flow and show preliminary results for the flow-time dependence of the CP-violating mixing angle $\alpha_N$ induced by the qCEDM between nucleon states.
These results are computed on the $N_f=2+1$ coarse lattice $16^3 \times 32$ with lattice spacing ($a \simeq 0.1215 fm$). We use Wilson-clover fermion with $\kappa=0.13825$ and $c_{SW}=1.761$.
