Magnetic Moments of Heavy Baryons
نویسندگان
چکیده
First non-trivial chiral corrections to the magnetic moments of triplet (T ) and sextet (S(∗)) heavy baryons are calculated using Heavy Hadron Chiral Perturbation Theory. Since magnetic moments of the T -hadrons vanish in the limit of infinite heavy quark mass (mQ → ∞), these corrections occur at order O(1/(mQΛχ)) for T -baryons while for S(∗)-baryons they are of order O(1/Λχ). The renormalization of the chiral loops is discussed and relations among the magnetic moments of different hadrons are provided. Previous results for T -baryons are revised.

Magnetic Moments of Baryons with a Single Heavy Quark
We calculate the magnetic moments of heavy baryons with a single heavy quark in the boundstate approach. In this approach the heavy baryons is considered as a heavy meson bound in the field of a light baryon. The light baryon field is represented as a soliton excitation of the light pseudoscalar and vector meson fields. For these calculations we adopt a model that is both chirally invariant and...
متن کاملA test of HHCPT using magnetic moments of heavy baryons
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/(mQΛχ)) for T -baryons and up to order O(1/Λχ) for S-baryons. The renormalization of the chiral loops is discussed and relations among the magnetic moments of different hadrons are ...
متن کاملThe magnetic moments of Λb and Λc baryons in light cone QCD sum rules
Using the most general form of the interpolating currents of heavy baryons, the magnetic moments of heavy baryons ΛQ (Q = b, c) are calculated in framework of the light cone QCD sum rules. A comparison of our results on magnetic moments with the existing theoretical results calculated in various other frameworks are presented.

متن کاملMagnetic moments of heavy baryons in the Skyrme model
We calculate the magnetic moments of heavy baryons in the Skyrme model in the limit of infinite heavy quark mass. We show that the Skyrme model yields the same limit as the nonrelativistic quark model when heavy vector mesons are treated properly. The essential role of the magnetic moment coupling terms in the electromagnetic interactions of heavy mesons is discussed. Typeset using REVTEX ∗On l...
متن کاملMasses and Magnetic Moments of Charmed Baryons Using Hyper Central Model
Heavy flavour baryons containing one or two charm quarks with light flavour combinations are studied using the hyper central description of the three-body system. The confinement potential is assumed as hyper central coulomb plus power potential with power index ν. The ground state masses and the magnetic moments of charmed, J = 1 2 + and 32 + baryons are computed for different power index, ν s...
