Abstract
In this paper we consider a new definition of improved fermion operators which is very convenient for numerical QCD simulations with the nearest-neighbour improved action, and we present the one-loop values of the corresponding renormalization constants. This redefinition includes terms that are formally of order a2 or higher and do not affect the conclusions about order a improvement.
