Magnetic Moments of the Octet Baryons in a Chiral Quark Potential Model†
نویسندگان
چکیده
In quark potential models, two–body current contributions to baryon magnetic moments arise necessarily to satisfy the continuity equation for the electromagnetic current. On the other hand, the näıve additive quark model predicts the experimental octet magnetic moments to within 5%. We demonstrate that consistently derived two–body current contributions to the octet baryon magnetic moments are individually large, but tend to cancel each other globally.

Baryon Magnetic Moments and Quark Orbital Motion in the Chiral Quark model
Using the unified scheme for describing both quark spin and orbital angular momenta in the chiral quark model developed in the previous work, the magnetic moments of octet and decuplet baryons are calculated. The numerical result shows that the overall agreement with data is improved by including the orbital contributions. 13.40.Em, 13.88.+e, 12.39.Fe, 14.20.Dh Typeset using REVTEX
متن کاملQuenched chiral perturbation theory for baryon form factors
A new intuitive method for the rapid calculation of the leading nonanalytic behavior of hadronic observables in quenched chiral perturbation theory is presented. After proving the technique in a consideration of baryon masses, the quenched magnetic moments of octet baryons are addressed. The technique provides a separation of magnetic moment contributions into full, sea, valence and quenched va...
متن کاملElectromagnetic form factors of the SU(3) octet baryons in the semibosonized SU(3) Nambu-Jona-Lasinio model.
The electromagnetic form factors of the SU(3) octet baryons are investigated in the semibosonized SU(3) Nambu–Jona-Lasinio model (chiral quark-soliton model). The rotational 1/N c and strange quark mass corrections in linear order are taken into account. The electromagnetic charge radii of the nucleon and magnetic moments are also evaluated. It turns out that the model is in * 1 a remarkable go...
متن کاملIncorporating Chiral Symmetry in Extrapolations of Octet Baryon Magnetic Moments
We explore methods of extrapolating lattice calculations of hadronic observables to the physical regime, while respecting the constraints of chiral symmetry and heavy quark effective theory. In particular, we extrapolate lattice results for magnetic moments of the spin-1/2 baryon octet to the physical pion mass and compare with experimental measurements. The success previously reported for extr...
متن کاملFlavor structure of the octet magnetic moments
We use the chiral quark-soliton model to identify all symmetry breaking terms linear in ms and investigate the strange magnetic moment in a “modelindependent” way. Assuming hedgehog symmetry and employing the collective quantization, we obtain the most general expression for the flavor-singlet and flavor-octet magnetic moments in terms of seven independent parameters. Having fitted these parame...
