Dimension-2 condensates, ζ-regularization and large- Nc Regge models
- 24 Downloads
Dimension-2 and -4 gluon condensates are re-analyzed in large-Nc Regge models with the ζ-function regularization which preserves the spectrum in any ¯q channel separately. We demonstrate that the signs and magnitudes of both condensates can be properly described within the framework.
