The calculation is performed in the chiral limit, and with two dynamical quark flavours. The ultraviolet behaviour of quantum loops involving virtual resonance propagators is analyzed, together with the kind of counterterms needed in the renormalization procedure. Using the lowest-order equations of motion, we show that only a few combinations of local couplings appear in the final result. The low-energy limit of our calculation reproduces the standard Chiral Perturbation Theory formula, allowing us to determine the resonance contribution to the chiral low-energy couplings, at the next-to-leading order in 1/NC, keeping a full control of their renormalization scale dependence.This work has been supported in part by the EU HPRN- CT2002-00311 (EURIDICE), by MCYT (Spain) under grant FPA-2001-303, by Generalitat Valenciana under grant GV04B-594 and by ERDF funds from the EU Commission.Peer reviewedInstitute of Physics Publishing201120112004info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501http://hdl.handle.net/10261/33105reponame:DIGITAL.CSIC.
