The Sigmac and Lamdac magnetic moments from QCD spectral sum rules
Abstract
We use QCD spectral sum rules to extract the Sigmac and Lambdac magnetic moments. The elctromagnetic field is treated as the external field. We adopt the value of the susceptibility chi=-4.5 GeV-2, which is determined from an overall analysis of the octet baryon magnetic moments. Our result for Sigmac is in agreement with the quark model prediction, while slight deviation exists from the Lambdac.
