A curious thing happened when MIT researchers Adam Vernon and Ronald Garcia Ruiz, along an international team of scientists, recently performed an experiment in which a sensitive laser spectroscopy te...
We elaborate on a recently proposed extension of the Gerasimov-Drell-Hearn (GDH) sum rule which is achieved by taking derivatives with respect to the anomalous magnetic moment. The new sum rule featur...
We calculate magnetic moments of light baryons and N→Δγ transition characteristics using a manifestly Lorentz covariant chiral quark approach for the study of baryons as bound states of constituent qu...
On neutrino-atom scattering in searches for neutrino magnetic moments
We report preliminary results for the magnetic moments of negative-parity baryons extracted from mass shifts in the presence of static external magnetic fields. The calculations are done on $24^3\time...
Measurements of the ground-state nuclear spins, magnetic and quadrupole moments of the copper isotopes from 61Cu up to 75Cu are reported. The experiments were performed at the ISOLDE facility, using t...
CaBaFe4O7 is a mixed-valent transition metal oxide having both Fe2+ and Fe3+ ions in tetrahedral coordination. Here we characterize its magnetic properties by magnetization measurements and investigat...
Recent work shows not only the necessity of a 1/Nc expansion to explain the observed mass spectrum of the lightest baryons, but also that at least two distinct large Nc expansions, in which quarks tr...
We report preliminary results for the magnetic moments of negative-parity baryons extracted from mass shifts in the presence of static external magnetic fields. The calculations are done on\ 243 48 ...
2005Vol.43No.1pp.139-146DOI: Magnetic Moments and Electromagnetic Radii of Nucleon and Δ(1232) in an Extended Goldstone- Boson-Exchange Model HE Jun1 and DONG Yu-Bing1,2 ...
We show that the systematic inconsistence found in the simultaneous fit of the neutron and proton magnetics moments in light-front models, disappears when one allows an asymmetry in the constituent qu...
The relevance of the pion mass, provenient from a term which explicitely breaks chiral symmetry in the Lagrangian, for nucleon magnetic moment in the frame work of the Skyrme model in two different ve...
