Baryon-decuplet magnetic moments
We investigate the generalized Coleman-Glashow sum rules in the magnetic moments of the baryon decuplet in the chiral bag model. Due to the spin symmetries held both for the effective and naive NRQMs in the SU(3) flavor symmetric limit, the chiral bag model can be considered as an effective NRQM with meson cloud as in the baryon octet. In thc multiquark structure with U-spin symmetry breaking, ...
متن کاملMagnetic moments of antidecuplet pentaquarks
We analyze the magnetic moments of the exotic pentaquarks of the flavor antidecuplet in the constituent quark model for the case in which the ground state is in an orbital L = 0 or a L = 1− state. We derive sum rules for the magnetic moments. The magnetic moment of the Θ(1540) is found to be 0.38, 0.09 and 1.05 μN for J p = 1/2−, 1/2 and 3/2, respectively, which is compared with the results obt...
متن کاملMagnetic Moments of Dirac Neutrinos
The existence of a neutrino magnetic moment implies contributions to the neutrino mass via radiative corrections. We derive model-independent "naturalness" upper bounds on the magnetic moments of Dirac neutrinos, generated by physics above the electroweak scale. The neutrino mass receives a contribution from higher order operators, which are renormalized by operators responsible for the neutrin...
متن کاملMagnetic Moments of Heavy Baryons
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 renormalizat...
متن کاملBounds on neutrino transition magnetic moments in random magnetic fields
We consider the conversions of active to sterile Majorana neutrinos νa and νs, due to neutrino transition magnetic moments in the presence of random magnetic fields (r.m.f.) generated at the electroweak phase transition. From a simple Schrödinger-type evolution equation, we derive a stringent constraint on the corresponding transition magnetic moments and display it as a function of the domain ...
