Magnetic moments of the proton and of octet baryons in a quasiparticle diquark model

Abstract
The strange contribution to the proton magnetic moment is investigated assuming a uudss¯ configuration for the proton in the context of a quasiparticle diquark model. The magnetic moment and mass of octet pentaquark baryons are also investigated considering the diquark-diquark-antiquark scheme. The results are found to be in agreement with the existing theoretical and experimental predictions. DOI: http://dx.doi.org/10.1103/PhysRevC.81.015202 © 2010 The American Physical Society
