The mass structure of SU(3) baryon antidecu- plet and pion muon mass difference
نویسنده
چکیده
We show that the mass intervals among the pentaquark baryons Θ, N∗(1685) and Ξ− 3/2 proposed to be the members of the SU(3) antidecuplet are exact integral multiples of the mass difference between a neutral pion and a muon i.e. 29.318 MeV. This is in agreement with the general tendency of the mass differences among elementary particles to be close integral/half integral multiple of mass difference between a neutral pion and a muon, the first two massive elementary particles.

Pentaquark baryons in SU(3) quark model
We study the SU(3) group structure of pentaquark baryons which are made of four quarks and one antiquark. The pentaquark baryons form 1, 8, 10, 10, 27, and 35 multiplets in SU(3) quark model. First, the flavor wave functions of all the pentaquark baryons are constructed in SU(3) quark model and then the flavor SU(3) symmetry relations for the interactions of the pentaquarks with three-quark bar...

We calculate the baryon octet masses to fourth order in chiral perturbation theory employing dimensional and cut-off regularization. We analyze the pion and kaon mass dependences of the baryon masses based on the MILC data. We show that chiral perturbation theory gives stable chiral extrapolation functions for pion (kaon) masses below 550 (600) MeV. The pion-nucleon sigma in SU(3) is also inves...
متن کاملPion and muon mass difference: a determining factor in elementary particle mass distribution
The most fundamental to the elementary particles is the mass they posses and it would be of importance to explore a possible relationship amongst their masses. Here, an attempt is made to investigate this important aspect irrespective of their nature or scheme of classification. We show that there exists a striking tendency for successive mass differences between elementary particles to be clos...
متن کاملThe 27-plet baryons with spin 3/2 under SU(3) symmetry
We investigate the spin 3/2 baryons in the 27-plet based on flavor SU(3) symmetry. For J = 3/2, we find all the candidates for non-exotic members. For J = 3/2−, we predict a new non-exotic member Λ(1780). Fitting the mass spectrum and calculating the widths of the members show an approximate symmetry of the 27-plet of SU(3). We find that the exotic members have relatively large widths and the Ξ...

In the approach to hadronic flavour symmetries based on the q-algebras U q (su N) and proved to be realistic, the known construction of U q (su N) in terms of anyonic oscillators residing on 2d lattice is utilized. Anyonic Fock-like realization of basis state vectors is given for baryons (3/2) + from the 10-plet of U q (su 3) embedded, via 20-plet of U q (su 4), into the " dynamical " represent...
