QCD Radiative Correction to Zero Recoil Sum Rules for Heavy Flavor Transitions in the Small Velocity Limit.

1995

We consider the small velocity sum rules for heavy flavour semileptonic transitions that are used to estimate the zero recoil values of semileptonic heavy flavour form factors. We analyze the complete O($\alpha _S$) radiative correction to these sum rules. The corrections are universal and influence all "model-independent" bounds previously derived for semileptonic form factors at zero recoil.

Erratum to: “Processes with a t-channel singularity in the physical region: finite beam sizes make cross sections finite”

2003

This affects the normalization of the “non-standard” cross-section, increasing it by thesame factor of two. As a consequence, Eq. (47), Fig. 3 and the estimate of the number ofneutrinos after Eq. (47) is modified accordingly.We are grateful to C. Dams and R. Kleiss for correspondencethat helped to uncoverthiserror.
