Dimension-2 condensates, zeta-regularization and large-Nc Regge Models
Enrique Ruiz Arriola, Wojciech Broniowski
Abstract
Dimension-2 and -4 gluon condensates are re-analyzed in large-Nc Regge models with the zeta-function regularization which preserves the spectrum in any q qbar channel separately. We demonstrate that the signs and magnitudes of both condensates can be properly described within the framework.
