Abstract
An all-order resummation is performed for the effect of the running of the coupling as in the zero-recoil sum rule for the axial current and for the kinetic operator π2. The perturbative corrections to well-defined objects of OPE turn out to be very moderate. The renormalization of the kinetic operator is addressed.
