Magnetic Moments of Baryons and Exotics in Quasi Particle Diquark Model

Abstract: The properties of the Θ + and Ξ −− 3/2 exotic baryons have been investigated in the framework of diquark-diquark-antiquark system. A model for diquark suggested in an analogy with the quasi-particle in a crystal lattice has been used. The mass of the exotics have been computed. The Decay width of the Θ + has been estimated to be ≃ 11 MeV using effective diquark theory. The radius of the Ξ −− 3/2 has been extracted as 0.94fm using the experimental value of the. The results obtained are found to be in good agree… Show more

“…Fermi momentum pf has been estimated using work of Bhattacharya et al [39,40]. The radii of diquarks are given input from existing literature [41][42][43]. With mu = md = 0.360GeV and ms = 0.54GeV from [44], Λ=0.573 GeV for light sector [45] the diquark masses have been estimated for Jp = ½ + and 3/2 + using the expression (2) and are furnished in Table-1.…”
