3 Aug 2015 | | Abstract: | The magnetic moments of $J^P=frac{3}{2}^+$ decuplet baryons have been
calculated in the chiral constituent quark model ($chi$CQM) with explicit
results for the contribution coming from the valence quark polarizations, sea
quark polarizations, and their orbital angular momentum. Since the
$J^P=frac{3}{2}^+$ decuplet baryons have short lifetimes, the experimental
information about them is limited. The $chi$CQM has important implications for
chiral symmetry breaking as well as SU(3) symmetry breaking since it works in
the region between the QCD confinement scale and the chiral symmetry breaking
scale. The predictions in the model not only give a satisfactory fit when
compared with the experimental data but also show improvement over the other
models. The effect of the confinement on quark masses has also been discussed
in detail and the results of $chi$CQM are found to improve further with the
inclusion of effective quark masses. | | Source: | arXiv, 1508.0308 | | Services: | Forum | Review | PDF | Favorites | |
