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...
Sum rules for magnetic moments and polarizabilities in QED and chiral effective-field theory
Anomalous magnetic moment the cross section of discrete integral number arsene wenger reproduction

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...
Light baryon magnetic moments and N ->Delta gamma transition in a Lorentz covariant chiral quark approach
Magnetic moment light baryons lorentz covariance baryons bound state pseudo-scalar meson
2014/12/20
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...

Magnetic Moments of Negative-Parity Baryons from Lattice QCD
Negative-Parity Baryons Lattice QCD
2011/1/7
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...
Nuclear spins, magnetic moments and quadrupole moments of Cu isotopes from N = 28 to N = 46: probes for core polarization effects
Nuclear spins magnetic moments quadrupole moments Cu isotopes probes core polarization effects
2010/12/31
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...
Orbital occupation and magnetic moments of tetrahedrally coordinated iron in CaBaFe4O7
Orbital occupation magnetic moments tetrahedrally coordinated iron
2010/11/25
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...

Baryon Magnetic Moments Alternate 1/N_c Expansions
2011/1/7
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...

Nucleon Magnetic Moments in Light-Front Models with Quark Mass Asymmetries
Nucleon Magnetic Moments Light-Front Models Quark Mass Asymmetries
2010/10/25
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...
