On the nature of the lowest 1/2 baryon nonet and decuplet
نویسنده
چکیده
From recent study of properties of the lowest spin-parity 1/2− baryons, N∗(1535) and ∆∗(1620), new pictures for the internal structure of the lowest 1/2− baryon octet and decuplet are proposed. While the lowest 1/2− baryon octet may have large diquark-diquark-antiquark component, the lowest 1/2− baryon decuplet is proposed to have large vector-meson-baryon components. Evidence for the “missing” members of the new pictures is pointed out and suggestions are made for detecting these predicted states from forthcoming experiments.

Exclusive Decuplet-Baryon Pair Production in Two-Photon Collisions
This work extends our previous studies of two-photon annihilation into baryon-antibaryon pairs from spin-1/2 octet to spin-3/2 decuplet baryons. Our approach is based on perturbative QCD and treats baryons as quarkdiquark systems. Using the same model parameters as in our previous work, supplemented by QCD sum-rule results for decuplet baryon wave functions, we are able to give absolute predict...
متن کاملExcited baryons from Bayesian priors and overlap fermions ∗ †
Using the constrained-fitting method based on Bayesian priors, we extract the masses of the two lowest states of octet and decuplet baryons with both parities. The calculation is done on quenched 16 3 × 28 lattices of a = 0.2 fm using an improved gauge action and overlap fermions, with the pion mass as low as 180 MeV. The Roper state N (1440) 1 2 + is clearly observed for the first time as the ...
متن کاملLarge-Nc operator analysis of 2-body meson-baryon counterterms in the chiral Lagrangian
The chiral SU(3) Lagrangian with the baryon octet and decuplet fields has been widely used in the literature. So far the sector of the chiral Lagrangian involving the decuplet fields is much less explored as compared to the sector involving the baryon octet fields. A new type of application was suggested in Ref. [1] where the leading order term involving the decuplet fields was used as the driv...
متن کاملSU ( 3 ) lattice QCD study for octet and decuplet baryon spectra ∗
The spectra of octet and decuplet baryons are studied using SU(3) lattice QCD at the quenched level. As an implementation to reduce the statistical fluctuation, we employ the anisotropic lattice with O(a) improved quark action. In relation to Λ(1405), we measure also the mass of the SU(3) flavor-singlet negative-parity baryon, which is described as a three quark state in the quenched lattice QC...
متن کاملThe lowest-lying spin-1/2 and spin-3/2 baryon magnetic moments in chiral perturbation theory
We review some recent progress in our understanding of the lowest-lying spin-1/2 and spin-3/2 baryon magnetic moments (MMs) in terms of Chiral Perturbation Theory (ChPT). In particular, we show that at next-to-leading-order ChPT can describe the MMs of the octet baryons quite well. We also make predictions for the decuplet MMs at the same chiral order. Among them, the MMs of the ∆ and ∆ are fou...
