QCD sum rules: Borel parameter vs. Euclidean time

A.V. Smilga

Euclidean-time sum rules for the nucleon yield rough mass and residue estimates but lack any usable fiducial window because power corrections and continuum contributions introduce larger uncertainties than in Borel sum rules.

Claims

C1strongest claim

A rough estimate of nucleon mass and residue is possible in coordinate space, but such sum rules are much more affected by uncertainties in power corrections and continuum contribution than the Borel ones: the fiducial interval is practically absent.

C2weakest assumption

That the size of the uncertainties assigned to the power corrections and continuum threshold in the Euclidean-time analysis is realistic and not underestimated relative to the Borel case.

C3one line summary

Euclidean-time sum rules for the nucleon yield rough mass and residue estimates but lack any usable fiducial window because power corrections and continuum contributions introduce larger uncertainties than in Borel sum rules.
