Abstract

First non-trivial chiral corrections to the magnetic moments of triplet (T) and sextet (S^(*)) heavy baryons are presented using Heavy Hadron Chiral Perturbation Theory. The contributions are calculated up to order \cal O(1/(m_Q Λ_χ²)) for T-baryons and up to order \cal O(1/Λ_χ²) for S^(*)-baryons. The renormalization of the chiral loops is discussed and relations among the magnetic moments of different hadrons are provided.
