Abstract
We present a fully non-perturbative determination of the O(a) improvement coefficient c_{\rm SW} in three-flavor dynamical QCD for the RG improved as well as the plaquette gauge actions, using the Schr\"odinger functional scheme. Results are compared with one-loop estimates at weak gauge coupling.
