ResumenWe investigate the lifetime of d holes in copper within afirst-principles GW approximation. At the G0W0 level the lifetime of the topmost d bands are in agreement with the experimental results and are four times smaller than those obtained in the >on-shell> calculations commonly used in literature. The theoretical lifetimes and band structure, however, worsen when further iterative steps of self-consistency are included in the calculation, pointing to a delicate interplay between self-consistency and the inclusion of vertex corrections. We show that the G0W0 success in the lifetimes calculation is due to the opening of >intraband> decay channels that disappear at self-consistency.
