A test of HHCPT using magnetic moments of heavy baryons

الأصل · EN

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 O(1/(mQ Λχ²)) for T-baryons and up to order O(1/Λχ²) for S⁽*⁾-baryons. The renormalization of the chiral loops is discussed and relations among the magnetic moments of different hadrons are provided.
