The (SigmaQ-LambdaQ) transition magnetic moments in light cone QCD sum rules
Abstract
Using the general form of (SigmaQ) and (LambdaQ) (Q=b or c) currents, (SigmaQ-LambdaQ) transition magnetic moments are calculated in framework of the light cone QCD sum rules method. In this approach nonperturbative effects are described by the photon wave functions and only two-particle photon wave functions are taken into account. Our predictions on transition magnetic moments are (muSigmac Lambdac = - (1.5 pm 0.4) muN) and (muSigmab Lambdab = - (1.6 pm 0.4) muN). A comparison of our results with the ones existing in the literature is given.
