Quadrupole moments of baryons

Abstract

Quadrupole moments of decuplet baryons and the octet-decuplet transition quadrupole moments are calculated using Morpurgo's general QCD parameterization method. Certain relations among the decuplet and the octet to decuplet transition quadrupole moments are derived. These can be used to predict the $\Delta$ quadrupole moments which are difficult to measure.
