Magnetic moments of heavy baryons - art. no. 074007

The first nontrivial chiral corrections to the magnetic moments of tripler (T) and sextet S-(*)) heavy baryons an calculated using heavy hadron chiral perturbation theory. Since magnetic moments of the T hadrons vanish in the limit of infinite heavy quark mass (m(Q)-->infinity), these corrections oc cur at order O(1/(m(Q)Lambda(x)(2))) for T baryons, while for S-(*) baryons they are of order (O(1/Lambda(x)(2)). The renormalization of the chiral lo ops is discussed, and relations among the magnetic moments of different had rons are provided. Previous results for T baryons are revised.
