Quadrupole moments of low lying baryons with spin 1/2^+, spin 3/2^+, and
spin 3/2^+ \to 1/2^+ transitions    [PDF]

Neetika Sharma, Harleen Dahiya

The chiral constituent quark model (\chiCQM) with general parameterization (GP) method has been formulated to calculate the quadrupole moments of the spin 3/2^+ decuplet baryons and spin 3/2^+ \to 1/2^+ transitions. The implications of such a model have been investigated in detail for the effects of symmetry breaking and GP parameters pertaining to the two- and three-quark contributions. It is found that the \chiCQM is successful in giving a quantitative and qualitative description of the quadrupole moments.
