BLM-Resummation and OPE in the Heavy Flavor Transitions

All-order resummation of the effect if running coupling $\alpha_s$ is performed for the zero recoil sum rule for the axial current and for the kinetic operator $\mu_\pi^2$. The perturbative corrections to well-defined objects of OPE proved to be very moderate. The renormalization of the kinetic oper...

The perturbative corrections to well-defined objects of OPE proved to be very moderate. The renormalization of the kinetic operator is addressed.An all-order resummation is performed for the effect of the running of the coupling alpha_s in the zero recoil sum rule for the axial current and for the kinetic operator vec{\pi}~2. The perturbative corrections to well-defined objects of OPE turn out to be very moderate. The renormalization of the kinetic operator is addressed.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 π 2 . The perturbative corrections to well-defined objects of OPE turn out to be very moderate. The renormalization of the kinetic operator is addressed.hep-ph/9610425UND-HEP-96-BIG04CERN-TH-96-304UND-HEP-96-BIG-04CERN-TH-96-304oai:cds.cern.ch:3132271996-10-20
