The One

A systematic method developed by us to evaluate the one-loop electromagnetic self-energies of the low-lying mesons is extended to the case of the ρ-meson. The theoretical prediction of ρ0-ρ± electromagnetic mass splitting is about 0.62 MeV, which is in agreement with the measurements.

Mixing Patterns

We construct a new version for the 3-3-1 model based on T7flavor symmetry where the left-handed leptons under T7differ from those of our previous work while the SU (3)C⊗ SU (3)L⊗ U (1)Xgauge symmetry is retained. The flavor mixing patterns and mass splitting are obtained without perturbation. The realistic lepton mixing can be obtained if both the direction of breakings T7→Z3and Z3→{ Identity } are taken place in neutrino sector. Maximal CP violation is predicted and Cabibbo–Kobayashi–Maskawa (CKM) matrix is the identity matrix at the tree-level.

Decays Of Baryons

Assuming that the baryon states are represented by supermultiplets of the oscillator excitation group U (6) × U (6) × U (3), we calculate the two-body decay widths of the lowest sub-multiplets, where the couplings are invariant under the collinear group U (6) × U (2). A simpli­fied model of octet–octet mixing is considered, which generally demonstrates the importance of mixing in controlling decay widths. Mass splitting is accounted for by using average SU (6) masses (for a given orbital excitation) in the couplings and physical masses to calculate the phase space factors of the decays.
