Description

By using techniques of unitarized chiral perturbation theory, where the Λ(1405) and Λ(1670) resonances are dynamically generated, we evaluate the magnetic moments of these resonances and their transition magnetic moment. The results obtained here differ appreciably from those obtained with existing quark models. The width for the Λ(1670)→Λ(1405)γ transition is also evaluated, leading to a branching ratio of the order of 2x10-6
